Systems and methods for retrieving segmented media guidance data

ABSTRACT

Systems and methods are presented for reducing network traffic when retrieving media guidance data. For example, a media guidance application receives a first user selection to display a group of media asset identifiers (e.g., video-on-demand listings) and retrieves detailed information from a remote server relating to the media asset identifiers to display to a user. The media guidance application then may receive a user selection to display a second group of media asset identifiers (e.g., purchased media assets). If any of the media asset identifiers are common to both groups, then the media guidance application already obtained the detailed information and the detailed information does not need to be retransmitted in order to be displayed. Thus, the media guidance application only retrieves detailed information for media asset identifiers unique to the second group of media asset identifiers (e.g., they are only on the purchased media asset list).

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional PatentApplication No. 62/423,395 filed Nov. 17, 2016, which is herebyincorporated by reference it its entirety.

BACKGROUND

Given the plethora of media content available to modern televisionconsumers, large data sets of media guidance data (i.e., data thatinforms users about media that can be consumed) often need to betransmitted to client devices (e.g., set-top boxes) from a contentprovider. The client device then may present the received media guidancedata to a user so that the user can be informed of what media assets areavailable. In some instances, particularly at times during the day whenmany users watch television, there are a large number of sessionsinitiated by client devices with servers of the content provider inorder to retrieve media guidance data. Due to the low-bandwidth natureof communication protocol between such systems, downloads of full setsof media guidance data took a significant amount of time. Prior systemsdealt with this problem in part through automatic updates stored at theset-top box at low traffic times. However, many client devices may notbe able to store detailed information for every media asset identifierthat could be presented to a user due to memory constraints, and thusneed to repeatedly transmit requests to the content provider fordetailed information for particular media asset identifiers. Thisprocess may drive up network traffic and ultimately affect performance.

SUMMARY

Accordingly, systems and methods are disclosed herein for reducingnetwork traffic when retrieving media guidance data. For example, amedia guidance application (e.g., executed on a set-top box) receives afirst user selection to display a group of media asset identifiers(e.g., video-on-demand listings) and retrieves detailed information froma server relating to the media asset identifiers to display to a user(e.g., from a remote server). The media guidance application then mayreceive a user selection to display a second group of media assetidentifiers (e.g., purchased media assets). If any of the media assetidentifiers are common to both groups, then the media guidanceapplication already obtained the detailed information and the detailedinformation does not need to be retransmitted in order to be displayed.Thus, the media guidance application only retrieves detailed informationfor media asset identifiers unique to the second group of media assetidentifiers (e.g., they are only on the purchased media asset list).

In some aspects, the media guidance application may receive a first userselection to navigate to a first group of media assets associated with afirst plurality of media asset identifiers. For example, the mediaguidance application may receive a user selection (e.g., via a userinput interface such as a remote control) to display a group of mediaasset identifiers. The group of media asset identifiers may be any setof related or unrelated media assets displayed to a user by the mediaguidance application. For example, the group of media asset identifiersmay be a user-defined list (e.g., a favorites list), a purchases list, avideo-on-demand catalog, a grid-guide showing a plurality of mediaassets from a plurality of sources, and any other criteria for groupinga plurality of media assets by the media guidance application.

The media guidance application may, in response to receiving the firstuser selection, retrieve, from a database containing media assetidentifiers associated with groups of media assets, a first plurality ofmedia asset identifiers corresponding to the first group of mediaassets. For example, the media guidance application may access a mediaguidance database containing media asset identifiers associated withgroups of media assets stored locally in storage or remote at a mediaguidance data source accessible via a communication network. The mediaguidance application may query the media guidance database for aspecific set of media asset identifiers associated with the first groupof media assets (e.g., a video-on-demand screen). For example, the mediaguidance application may execute a program script utilizing a databasequery language such as SQL to determine whether an entry for the groupof media assets is present in the media guidance database and toretrieve pointers to media asset identifiers stored in fields associatedwith the entry. The media guidance application may then retrieve theidentifiers from memory based on the pointers.

The media guidance application may, in response to receiving the firstuser selection, store in a local storage device respective detailedinformation retrieved from a remote server for each of the firstplurality of media asset identifiers. For example, the media guidanceapplication may transmit a request or plurality of requests for detailedinformation for each of the media assets identifiers to the remoteserver (e.g., a media guidance data source via a communication network).As a specific example, the media guidance application may transmit adata packet to the remote server containing one or more identifiers andmay receive the detailed information corresponding to the one or moreidentifiers. The media guidance application then stores the retrieveddetailed information. In some embodiments, the media guidanceapplication stores the retrieved detailed information in non-volatilememory (e.g., flash memory) if it is available. In other embodiments,the media guidance application stores the retrieved detailed informationin volatile memory (e.g., SRAM).

The media guidance application may receive a second user selection tonavigate to a second group of media assets associated with a secondplurality of media asset identifiers. For example, the media guidanceapplication may receive a user input (e.g., via a user input interfacesuch as a touch screen) selecting a different group of media assets. Forexample, the media guidance application may first have received arequest to view media assets identifiers in a video-on-demand guide andlater receives a request to view media asset purchases. In someembodiments, the second plurality of media asset identifiers are storedin memory. For example, the media guidance application may be unable tostore detailed information relating to media assets a user haspurchased, but may be able to locally store (e.g., in non-volatilememory) identifiers of media assets the user has purchased. As the mediaguidance application retrieves detailed information during a session,some of the retrieved detailed information may pertain to the purchasedmedia assets and thus would not need to be retrieved again, as describedfurther below.

The media guidance application, in response to receiving the second userselection, determines whether the media asset identifiers overlapbetween the first and second groups and determines where to retrievedetailed information for the media asset identifiers of the second groupbased on whether the media asset identifiers overlap. The media guidanceapplication may retrieve, from the database containing media assetidentifiers associated with groups of media assets, a second pluralityof media asset identifiers corresponding to the second group of mediaassets. For example, as discussed above with respect to retrieving thefirst plurality of media asset identifiers, the media guidanceapplication may similarly retrieve the second group of media assetidentifiers. For example, the media guidance application may access themedia guidance database containing media asset identifiers associatedwith groups of media assets stored locally in storage or remote at amedia guidance data source accessible via a communication network. Themedia guidance application may query the media guidance database for aspecific set of media asset identifiers associated with the second groupof media assets (e.g., a purchases screen) and retrieve the identifiers.

The media guidance application may compare a first respective entry inthe database for each media asset identifier of the first plurality ofmedia asset identifiers with a second respective entry in the databasefor each media asset identifier of the second plurality of media assetidentifiers. For example, the media guidance application may execute aprogram script containing a for-loop to iteratively compare each mediaasset identifier in the first plurality of media asset identifiers andeach media asset identifier in the second plurality of media assetidentifiers. The media guidance application may retrieve data stored inentries associated with each media asset identifier of the first andsecond plurality of media asset identifiers to compare. For example, themedia guidance application may retrieve from the database characters ofmedia asset identifiers and/or metadata associated with the media assetidentifiers to compare.

The media guidance application may determine a first subset of mediaasset identifiers, the first subset including each media assetidentifier of the second plurality of media asset identifiers where datain the first respective entry matches data in the second respectiveentry. For example, the media guidance application may store anindication (e.g., on a list or other data structure) containing anidentifier of each media asset identifier of the second plurality ofmedia asset identifiers where a match between the first plurality ofmedia asset identifiers and second plurality of media asset identifiershas been determined. Specifically, the media guidance application maydetermine a match based on comparing characters of two media assetidentifiers (e.g., retrieved by the media guidance application fromentries associated with the media asset identifiers in the database) anddetermining each character is identical and in the same order (e.g.,based on indexing the characters). Upon determining a match, the mediaguidance application may execute an instruction to write an identifierof the matched media asset identifier to a list defining the firstsubset.

In some embodiments, the media guidance application may retrieve thedetailed information of matched media asset identifiers (e.g., mediaasset identifiers determined to be in the first subset) in parallel withdetermining whether other media asset identifiers are in the firstsubset. For example, while continuing to loop through every entrycorresponding to a media asset identifier of the first and secondplurality of media asset identifiers and identify matches, each time amatch is found the media guidance application may simultaneouslyretrieve the detailed information from local storage, as describedfurther below. In this embodiment, the media guidance application maygenerate for display a partially complete display screen with detailedinformation for the second plurality of media asset identifiers that arepart of the first subset while detailed information for other mediaasset identifiers is still being retrieved, which may quickly andefficiently provide detailed information to a user.

The media guidance application may determine a media asset identifier ispart of the first subset in a variety of ways. In some embodiments, themedia guidance application may retrieve, from the database, charactersof a first media asset identifier of the first plurality of media assetidentifiers in a first entry and characters of a second media assetidentifier of the second plurality of media asset identifiers in asecond entry. For example, the media guidance application may retrieve(e.g., by executing an SQL program script utilizing the “Select”command) a string of characters (e.g., “James Bond: Goldfinger”)associated with a first media asset identifier of the first plurality ofmedia asset identifiers (e.g., video-on-demand listings) and a string ofcharacters (e.g., “James Bond: Casino Royale”) associated with a secondmedia asset identifier of the second plurality of media assetidentifiers (e.g., recent purchases). The media guidance applicationthen may compare the characters of the first media asset identifier withthe characters of the second media asset identifier. For example, themedia guidance application may compare indexed characters of theretrieved strings to determine whether each character matches. Forexample, the media guidance application may determine that the first tencharacters (e.g., “James Bond:”) match, but the subsequent characters donot (e.g., no indexed character of “Goldfinger” matches thecorresponding indexed character of “Casino Royale”).

The media guidance application may then determine whether the charactersof the first media asset identifier match the characters of the secondmedia asset identifier. For example, as described above, the mediaguidance application may determine whether each indexed character of thecharacters associated with the first media asset identifier matches acorresponding character of the characters associated with the secondmedia asset identifier. The media guidance application may then, inresponse to determining the characters of the first media assetidentifier match the characters of the second media asset identifier,determine the first media asset identifier corresponds to the secondmedia asset identifier. For example, the media guidance application maydetermine that since all the characters match, the media assetidentifiers match and thus the second media asset identifier is part ofthe first subset (e.g., detailed information is already stored locally).

In some embodiments, when determining whether a threshold number ofcharacters match, the media guidance application may skip a series ofcharacters that do not match if a latter series of characters do match.For example, the media guidance application would determine “Star Wars:First Episode” does not match the word “Episode” with a second string ofcharacters “Star Wars: Episodes I” based on comparing solely thecharacter indexes. However, by skipping the indices of “First” in thefirst string, the indices for “Episode” line up leading to the mediaguidance application determining a greater number of matched characters.

Alternatively or additionally, the media guidance application may, inresponse to determining that the characters of the first media assetidentifier do not match the characters of the second media assetidentifier, determine whether a threshold amount of the characters ofthe first media asset identifier match the characters of the secondmedia asset identifier. For example, the media guidance application maydetermine a number or percentage (e.g., 80%) of characters that matchbetween the characters of the first media asset identifier and thecharacters of the second media asset identifier. The media guidanceapplication may then compare this to a threshold number or percentage ofmatched characters (e.g., 70%) and determine whether the amount orpercentage of characters matched between the first media assetidentifier and the second media asset identifier exceeds the threshold.

The media guidance application may, in response to determining that thethreshold amount of the characters of the first media asset identifiermatch the characters of the second media asset identifier, retrievemetadata associated with the first media asset identifier and metadataassociated with the second media asset identifier. For example, upondetermining that the threshold amount or percentage of charactersmatched is exceeded by the characters of first and second media assetidentifiers, the media guidance application may retrieve metadataassociated with the first and second media asset identifiers. Themetadata may be any data relating to the media asset identifier,including some or all of the associated detailed information. As anexample, the first media asset identifier may be “Star Wars: Episode I”and the second media asset identifier may be “Star Wars: First Episode.”Despite the differences between identifiers (e.g., based on charactercomparison as described above), the media guidance application maydetermine the two media asset identifiers match based on metadata (e.g.,the actors and director) matching between the two identifiers since athreshold number of characters match.

The media guidance application may then compare the metadata associatedwith the first media asset identifier and the metadata associated withthe second media asset identifier. For example, the media guidanceapplication may compare a string of characters for the directorassociated with the first media asset identifier and the second mediaasset identifier (e.g., “George Lucas” and “George Miller”) in the samemanner as discussed above for comparing characters of the media assetidentifiers. The media guidance application may then determine whetherthe metadata associated with the first media asset identifiercorresponds to the metadata associated with the second media assetidentifier. For example, the media guidance application may determinewhether the metadata corresponds based on whether all, or a thresholdnumber or percentage, of characters of the metadata associated with thefirst and second media asset identifier are matched. The media guidanceapplication, in response to determining the metadata associated with thefirst media asset identifier matches the metadata associated with thesecond media asset identifier, determines the first media assetidentifier corresponds to the second media asset identifier. Forexample, the media guidance application may determine that since athreshold amount of the characters match and that the metadata matches,the media asset identifiers match and thus the second media assetidentifier is part of the first subset (e.g., detailed information isalready stored locally). In some embodiments, if either the metadata orthreshold amount of characters of the media asset identifiers match, butnot both, the media guidance application may determine that the mediaasset identifiers are related and a subset of the detailed informationbetween the two media asset identifiers corresponds and can be retrievedfrom local storage, but some detailed information may be retrieved froma remote server (e.g., if the media asset identifiers are differentepisodes of a series, the director and actors may be the same but thesummary may be different).

Alternatively or additionally, the media guidance application may, inresponse to determining that the characters of the first media assetidentifier do not match the characters of the second media assetidentifier, access a data structure containing indications of whethermedia asset identifiers are associated. For example, the media guidanceapplication may access a data structure containing equivalentidentifiers which may be organized as a table where each entry (e.g.,row) contains identifiers that are associated with the same media asset.The media guidance application may then retrieve an entry in the datastructure for the first media asset identifier. For example, the mediaguidance application may execute an instruction (e.g., an SQL programscript utilizing the “Select” command) to retrieve, from an entry for afirst media asset identifier, all other associated media assetidentifiers (e.g., from fields associated with the entry).

The media guidance application may then determine, based on data in theentry identifying the second media asset identifier, that the secondmedia asset identifier is associated with the first media assetidentifier. For example, the media guidance application may retrieve,from fields associated with an entry for the media asset identifier“Star Wars: Episode I,” media asset identifiers “Star Wars: FirstEpisode,” and “Star Wars: Ep. 1” indicated as equivalent media assetidentifiers. Based on comparing (e.g., by character comparison asdescribed above) the second media asset identifier to the retrievedequivalent identifiers, the media guidance application can determinewhether they are associated. The media guidance application may, inresponse to determining the first media asset identifier is associatedwith the second media asset identifier, determine a subset of thedetailed information for the second media asset identifier that matchesthe first media asset identifier. As described further below, when twomedia asset identifiers are related or associated, but do not exactlymatch, some detailed information may be common to both identifiers andsome may not. For example, the media guidance application may store alist of detailed information that is common between media assetidentifiers determined to be related or associated, such as actors. Themedia guidance application may retrieve the subset of detailedinformation from local storage.

In some embodiments, the media guidance application may determine thedetailed information for the second media asset identifier not retrievedfrom the local storage device. For example, as described above, themedia guidance application may determine that a subset of detailedinformation (e.g., actor names) is common to both the first and secondmedia asset identifiers. However, some detailed information (e.g., asummary) may not be common to both. In this situation, the mediaguidance application retrieves the detailed information for the secondmedia asset identifier not retrieved from the local storage device fromthe remote server. The media guidance application thus can generate afull set of detailed information for the second media asset identifierfor display without having to retrieve all of the information (which maycause delays/increase network traffic) from the remote server.

In some embodiments, the media guidance application may determine that afirst media asset identifier of the first plurality of media assetidentifiers is related, but not identical, to a second media assetidentifier of the second plurality of media asset identifiers. Forexample, the media guidance application may determine, as describedabove, that the first and second media asset identifiers are notidentical because of a difference in their characters. However, themedia guidance application may determine that the two media assetidentifiers are related or associated (e.g., based on a threshold numberof characters matching, metadata corresponding, and/or a storedindication the two identifiers are related). For example, the firstmedia asset identifier may be for “Star Wars: Episode II” and the secondmedia asset identifier may be for “Star Wars: Episode III.” While notidentical, the media guidance application may determine that since thetwo media asset identifiers are related based on an indication that theyare part of a series, some of the detailed information may be relevant.The media guidance application may then determine to retrieve a subsetof the detailed information from the first media asset identifier todisplay with the second media asset identifier instead of transmitting arequest to the remote server for the detailed information. As a specificexample, the media guidance application may determine from a datastructure that media asset identifiers that are part of a series oftenhave the same actors, directors, and genres but not the same title orsummary. Accordingly, the media guidance application may retrieve theactor, director and genre for “Star Wars: Episode II” and generate themfor display with the identifier for “Star Wars: Episode III,” thussaving a transaction with the remote server. In some embodiments, themedia guidance application stores whether to request detailedinformation for related media assets as a user configurable option(e.g., via a button in a user interface) that can be toggled on or off.

The media guidance application may determine a second subset of mediaasset identifiers, the second subset including each media assetidentifier of the second plurality of media asset identifiers where datain the first respective entry does not match data in the secondrespective entry. For example, the media guidance application mayexecute the program script described above for comparing media assetidentifiers in the first and second plurality of media asset identifiersand sort any media asset identifiers unique to the second plurality ofmedia asset identifiers into a list or other data structure (e.g., thesecond subset). For example, the media guidance application may, foreach media asset identifier of the second plurality, retrieve data tocompare from every media asset identifier of the first plurality. Ifnone of the data compared (e.g., characters of the identifiers) match,then the media guidance application may execute an instruction to writean identifier of the media asset identifier for which none of the datamatches to a list or other data structure defining the second subset(e.g., where detailed information has not already been retrieved fromthe remote server).

The media guidance application may then retrieve detailed informationfor each media asset identifier in the first subset of media assetidentifiers from the local storage device. For example, the mediaguidance application has already retrieved the detailed information foreach media asset identifier in the first subset from the remote server(e.g., media guidance data source). The media guidance application maystore the detailed information in volatile memory (e.g., DRAM or SRAM)due to not having enough non-volatile memory available to store thedetailed information permanently. Since the detailed information hasalready been retrieved for each media asset in the second subset, themedia guidance application retrieves the detailed information from thecorresponding blocks of memory where it is stored instead oftransmitting a request for the detailed information to the remoteserver, minimizing transactions with the remote server and alsomaximizing the speed at which the second group of media assetidentifiers can be loaded.

The media guidance application may then retrieve detailed informationfor each media asset identifier in the second subset of media assetidentifiers from a remote server. For example, for media assetidentifiers where the detailed information has not been receivedpreviously (i.e., each media asset identifier in the second subset), themedia guidance application retrieves the detailed information from theremote server. For example, as described above for retrieving detailedinformation for the first plurality of media assets, the media guidanceapplication transmits a data packet to a remote server containing eachmedia asset identifier in the second subset. For example, the mediaguidance application may transmit the data packet including a singlemedia asset identifier or a list or other suitable data structure ofmedia asset identifiers. The media guidance application may thenreceive, from the remote server, the detailed information for each mediaasset identifier in the second subset.

In some embodiments, the media guidance application may determine that athird plurality of media asset identifiers are stored on the localstorage device. For example, the media guidance application may haveretrieved detailed information about a third group of media assets andmay determine whether any detailed information retrieved for the thirdplurality of media asset identifiers overlaps with the second pluralityof media asset identifiers. The media guidance application may thendetermine a third subset of media asset identifiers that are in both thesecond plurality of media asset identifiers and the third plurality ofmedia asset identifiers. As described above when determining the firstsubset, the media guidance application may determine whether each mediaasset identifier of the second plurality of media asset identifiersmatches one of the media asset identifiers of the third plurality andstore an indication on a list or other data structure for each mediaasset identifier that matches. The media guidance application may thenretrieve detailed information for each media asset identifier in thethird subset of media asset identifiers from the local storage device.For example, as described above for the first subset, the media guidanceapplication may retrieve detailed information from the local storagedevice since it has already been retrieved when the third plurality ofmedia asset identifiers were previously displayed.

In some embodiments, the media guidance application retrieves atimestamp for detailed information for a first media asset identifier inthe first subset stored on the local storage device. For example, themedia guidance application may store a timestamp (e.g., the date andtime) that detailed information for a media asset identifier wasretrieved. The media guidance application may maintain a data structurewith timestamps of when detailed descriptions were retrieved, or thetimestamps may be stored with the detailed information (e.g., as a fieldin a table containing the detailed information). The media guidanceapplication may determine, by subtracting the timestamp from the currenttime, whether the detailed information for the first media assetidentifier exceeds a threshold amount of time stored. For example, themedia guidance application may determine that the current time is 15:31on 05-31-2016 (e.g., May 31, 2016) and the detailed information wasretrieved at 10:31 on 05-24-2016. The media guidance application maydetermine the amount of time elapsed since retrieval of the detailedinformation by subtracting the individual values (e.g., 05 from 05, 24from 31, etc.). As an example, the media guidance application maycalculate that the time elapsed is five hours past one week (e.g., sevendays and five hours). The media guidance application may then comparethis value to a threshold value (e.g., five days) to determine whetherthe elapsed time exceeds the threshold time.

The media guidance application may then, in response to determining thatthe detailed information for the first media asset identifier exceedsthe threshold amount of time stored, delete the detailed information forthe first media asset identifier stored on the local storage device. Forexample, the media guidance application may delete the detailedinformation from the local storage device as opposed to retrieving it ifthe elapsed time is greater than the threshold time. The media guidanceapplication may then retrieve new detailed information for the firstmedia asset identifier from the remote server. For example, as describedabove, the media guidance application may transmit a request fordetailed information relating to the media asset identifier to a remoteserver. The media guidance application may then receive detailedinformation associated with the media asset identifier (e.g., in a datapacket) from the remote server. The media guidance application may thenstore the new detailed information for the first media identifier on thelocal storage device.

In some embodiments, the media guidance application may generate fordisplay a plurality of options for types of detailed information toretrieve. For example, the media guidance application may generate auser interface including a plurality of options to customize what typesof information is retrieved from a remote server. For example, theoptions may be for types of detailed information such as an option tonot retrieve detailed information of type “actor,” “director,” “summary”or any other subset of the detailed information. The media guidanceapplication may then receive a user input of a first option to notretrieve a first type of detailed information if it is not stored in thelocal storage device. For example, the media guidance application mayreceive a user input (e.g., via a user input interface) of an option tonot retrieve detailed information for type “actor.” The media guidanceapplication may, in response to receiving the user input, store anindication in the local storage device to only retrieve the first typeof detailed information if it is stored in the local storage device. Forexample, the media guidance application may store (e.g., in a datastructure) an indication that unless “actor” information is storedlocally, it is not to be retrieved (e.g., not retrieved from a remoteserver). In this way, the media guidance application allows the user tocustomize the information that is retrieved and stored and moreefficiently manage storage on a storage device with limited capacity.

It should be noted the systems and/or methods described above may beapplied to, or used in accordance with, other systems, methods and/orapparatuses.

DETAILED DESCRIPTION

Systems and methods are disclosed herein for reducing network trafficwhen retrieving media guidance data. For example, a media guidanceapplication (e.g., executed on a set-top box) receives a first userselection to display a group of media asset identifiers (e.g.,video-on-demand listings) and retrieves detailed information from aserver relating to the media asset identifiers to display to a user(e.g., from a remote server). The media guidance application then mayreceive a user selection to display a second group of media assetidentifiers (e.g., purchased media assets). If any of the media assetidentifiers are common to both groups, then the media guidanceapplication already obtained the detailed information and the detailedinformation does not need to be retransmitted in order to be displayed.Thus, the media guidance application only retrieves detailed informationfor media asset identifiers unique to the second group of media assetidentifiers (e.g., they are only on the purchased media asset list).

FIG. 1 shows an illustrative example of reducing network traffic whenretrieving media guidance data, in accordance with some embodiments ofthe disclosure. For example, display 100 and display 112 may bepresenting a media guidance application used by a user to navigate mediaasset identifiers (e.g., listings), as described further below withrespect to FIGS. 2-3. Display 100 and display 112 may appear on one ormore user devices (e.g., any of the devices listed in FIGS. 4-5 below).Moreover, the media guidance application may use the process describedin FIG. 6 below to generate display 100 or display 112 or any of thefeatures described therein.

Display 100 includes first group of media asset identifiers 102 (e.g.,video-on-demand (“VOD”) listings). For example, the media guidanceapplication may retrieve from a media guidance data source a list ofmedia asset identifiers (e.g., media asset identifiers 104, 108, and110) which are available for a user to purchase. Each media assetidentifier may have associated detailed information to help a userdecide whether to purchase the media asset. For example, the mediaguidance application generates for display media asset identifier 104with associated detailed information 106, which may be retrieved asdescribed further below. As referred to herein, “detailed information”should be understood as any data that describes media assets. Forexample, the data may be any metadata related to the media assetidentifier, such as a summary, title, content rating, and actors.

Display 112 includes second group of media asset identifiers 114 (e.g.,a list of purchased media assets). The media guidance application maypresent display 112 after a user selection to leave first group of mediaasset identifiers 102 and navigate to second group of media assetidentifiers 114. For example, as described further below, since themedia guidance application already retrieved detailed information formedia asset identifier 104 and media asset identifier 104 is identicalto media asset identifier 116, the media guidance application retrievesdetailed information 106 from memory (e.g., SRAM or DRAM) and generatesit for display as detailed information 118. For media asset identifiers(e.g., media asset identifiers 120) where the detailed descriptions werenot previously retrieved, the media guidance application retrieves thedetailed descriptions from the remote server, as described furtherbelow.

The media guidance application may receive a first user selection tonavigate to a first group of media assets associated with a firstplurality of media asset identifiers. For example, the media guidanceapplication may receive a user selection (e.g., via a user inputinterface such as a remote control) to display a group of media assetidentifiers (e.g., first group of media asset identifiers 102). Thegroup of media asset identifiers may be any set of related or unrelatedmedia assets displayed to a user by the media guidance application. Forexample, the group of media asset identifiers may be a user defined list(e.g., a favorites list, a purchases list, a video-on-demand catalog, agrid-guide showing a plurality of media assets from a plurality ofsources, and any other criteria for grouping a plurality of media assetsby the media guidance application).

The media guidance application may, in response to receiving the firstuser selection, retrieve, from a database containing media assetidentifiers associated with groups of media assets, a first plurality ofmedia asset identifiers corresponding to the first group of mediaassets. For example, the media guidance application may access a mediaguidance database containing media asset identifiers associated withgroups of media assets stored locally in storage or remote at a mediaguidance data source accessible via a communication network. The mediaguidance application may query the media guidance database for aspecific set of media asset identifiers (e.g., media asset identifiers104, 108, and 110) associated with the first group of media assets(e.g., first group of media asset identifiers 102). For example, themedia guidance application may execute a program script utilizing adatabase query language such as SQL to determine whether an entry forthe group of media assets (e.g., first group of media asset identifiers102) is present in the media guidance database and to retrieve pointersto media asset identifiers (e.g., media asset identifiers 104, 108, and110) stored in fields associated with the entry. The media guidanceapplication may then retrieve the identifiers (e.g., media assetidentifiers 104, 108, and 110) from memory based on the pointers.

The media guidance application may, in response to receiving the firstuser selection, store in a local storage device respective detailedinformation retrieved from a remote server for each of the firstplurality of media asset identifiers. For example, the media guidanceapplication may transmit a request or plurality of requests for detailedinformation (e.g., detailed information 106) for each of the mediaassets identifiers (e.g., media asset identifiers 104, 108, and 110) tothe remote server (e.g., a media guidance data source via acommunication network). As a specific example, the media guidanceapplication may transmit a data packet to the remote server containingone or more identifiers (e.g., media asset identifiers 104, 108, and110) and may receive the detailed information (e.g., detailedinformation 106) corresponding to the one or more identifiers. The mediaguidance application then stores the retrieved detailed information. Insome embodiments, the media guidance application stores the retrieveddetailed information in non-volatile memory (e.g., flash memory) if itis available. In other embodiments, the media guidance applicationstores the retrieved detailed information in volatile memory (e.g.,SRAM).

The media guidance application may receive a second user selection tonavigate to a second group of media assets associated with a secondplurality of media asset identifiers. For example, the media guidanceapplication may receive a user input (e.g., via a user input interfacesuch as a touch screen) selecting a different group of media assets(e.g., second group of media asset identifiers 114). For example, themedia guidance application may first have received a request to viewmedia assets identifiers in a video-on-demand guide (e.g., first groupof media asset identifiers 102) and later receives a request to viewmedia asset purchases (e.g., second group of media asset identifiers114). In some embodiments, the second plurality of media assetidentifiers are stored in memory. For example, the media guidanceapplication may be unable to store detailed information relating tomedia assets a user has purchased, but may be able to locally store(e.g., in non-volatile memory) identifiers (e.g., media asset identifier116) of media assets the user has purchased (e.g., second group of mediaasset identifiers 114). As the media guidance application retrievesdetailed information (e.g., detailed information 118) during a session,some of the retrieved detailed information may pertain to the purchasedmedia assets and thus would not need to be retrieved again, as describedfurther below.

The media guidance application, in response to receiving the second userselection, determines whether the media asset identifiers overlapbetween the first and second groups and determines where to retrievedetailed information for the media asset identifiers of the second groupbased on whether the media asset identifiers overlap. The media guidanceapplication may retrieve, from the database containing media assetidentifiers associated with groups of media assets, a second pluralityof media asset identifiers corresponding to the second group of mediaassets. For example, as discussed above with respect to retrieving thefirst plurality of media asset identifiers, the media guidanceapplication may similarly retrieve the second group of media assetidentifiers (e.g., media asset identifiers 116 and 120). For example,the media guidance application may access the media guidance databasecontaining media asset identifiers associated with groups of mediaassets stored locally in storage or remote at a media guidance datasource accessible via a communication network. The media guidanceapplication may query the media guidance database for a specific set ofmedia asset identifiers associated with the second group of media assets(e.g., a purchases screen) and retrieve the identifiers (e.g., mediaasset identifiers 116 and 120).

The media guidance application may compare a first respective entry inthe database for each media asset identifier of the first plurality ofmedia asset identifiers with a second respective entry in the databasefor each media asset identifier of the second plurality of media assetidentifiers. For example, the media guidance application may execute aprogram script containing a for-loop to iteratively compare each mediaasset identifier (e.g., media asset identifiers 104, 108, and 110) inthe first plurality of media asset identifiers and each media assetidentifier (e.g., media asset identifiers 116 and 120) in the secondplurality of media asset identifiers. The media guidance application mayretrieve data stored in entries associated with each media assetidentifier of the first and second plurality of media asset identifiersto compare. For example, the media guidance application may retrievefrom the database characters of media asset identifiers and/or metadataassociated with the media asset identifiers to compare.

The media guidance application may determine a first subset of mediaasset identifiers, the first subset including each media assetidentifier of the second plurality of media asset identifiers where datain the first respective entry matches data in the second respectiveentry. For example, the media guidance application may store anindication (e.g., on a list or other data structure) containing anidentifier of each media asset identifier of the second plurality ofmedia asset identifiers (e.g., media asset identifier 116) where a matchbetween the first plurality of media asset identifiers and secondplurality of media asset identifiers has been determined (e.g., anindication may be stored for media asset identifiers 116 and 104).Specifically, the media guidance application may determine a match basedon comparing characters of two media asset identifiers (e.g., retrievedby the media guidance application from entries associated with the mediaasset identifiers in the database) and determining each character isidentical and in the same order (e.g., based on indexing thecharacters). Upon determining a match, the media guidance applicationmay execute an instruction to write an identifier of the matched mediaasset identifier (e.g., media asset identifier 116) to a list definingthe first subset.

In some embodiments, the media guidance application may retrieve thedetailed information of matched media asset identifiers (e.g., mediaasset identifiers determined to be in the first subset) in parallel withdetermining whether other media asset identifiers are in the firstsubset. For example, while continuing to loop through every entrycorresponding to a media asset identifier of the first and secondplurality of media asset identifiers (e.g., first group of media assetidentifiers 102 and second group of media asset identifiers 114) andidentify matches, each time a match is found (e.g., between media assetidentifier 104 and 116) the media guidance application maysimultaneously retrieve the detailed information (e.g., detailedinformation 106) from local storage, as described further below. In thisembodiment, the media guidance application may generate for display apartially complete display screen with detailed information (e.g.,detailed information 118) for the second plurality of media assetidentifiers that are part of the first subset while detailed informationfor other media asset identifiers (e.g., media asset identifiers 120) isstill being retrieved, which may more quickly and efficiently providedetailed information to a user.

The media guidance application may determine a media asset identifier ispart of the first subset in a variety of ways. In some embodiments, themedia guidance application may retrieve, from the database, charactersof a first media asset identifier (e.g., media asset identifier 104) ofthe first plurality of media asset identifiers in a first entry andcharacters of a second media asset identifier (e.g., media assetidentifier 116) of the second plurality of media asset identifiers in asecond entry. For example, the media guidance application may retrieve(e.g., by executing a SQL program script utilizing the “Select” command)a string of characters (e.g., “The Martian”) associated with a firstmedia asset identifier (e.g., media asset identifier 104) of the firstplurality of media asset identifiers (e.g., first group of media assetidentifiers 102) and a string of characters (e.g., “The Martian”)associated with a second media asset identifier (e.g., media assetidentifier 116) of the second plurality of media asset identifiers(e.g., second group of media asset identifiers 114). The media guidanceapplication then may compare the characters of the first media assetidentifier with the characters of the second media asset identifier. Forexample, the media guidance application may compare indexed charactersof the retrieved strings to determine whether each character matches.For example, the media guidance application may determine that everyindexed character matches between the first and second media assetidentifiers (e.g., media asset identifiers 104 and 116).

The media guidance application may then determine whether the charactersof the first media asset identifier match the characters of the secondmedia asset identifier. For example, as described above, the mediaguidance application may determine whether each indexed character of thecharacters associated with the first media asset identifier (e.g., mediaasset identifier 104) matches a corresponding character of thecharacters associated with the second media asset identifier (e.g.,media asset identifier 116). The media guidance application may then, inresponse to determining the characters of the first media assetidentifier match the characters of the second media asset identifier,determine the first media asset identifier corresponds to the secondmedia asset identifier. For example, the media guidance application maydetermine that since all the characters match, the media assetidentifiers match and thus the second media asset identifier is part ofthe first subset (e.g., detailed information is already stored locally).

In some embodiments, when determining whether a threshold number ofcharacters match, the media guidance application may skip a series ofcharacters that do not match if a latter series of characters do match.For example, the media guidance application would determine “Star Wars:First Episode” does not match the word “Episode” with a second string ofcharacters “Star Wars: Episodes I” based on comparing solely thecharacter indexes. However, by skipping the indices of “First” in thefirst string, the indices for “Episode” line up leading to the mediaguidance application determining a greater number of matched characters.

Alternatively or additionally, the media guidance application may, inresponse to determining that the characters of the first media assetidentifier do not match the characters of the second media assetidentifier, determine whether a threshold amount of the characters ofthe first media asset identifier match the characters of the secondmedia asset identifier. For example, the media guidance application maydetermine a number or percentage (e.g., 80%) of characters that matchbetween the characters of the first media asset identifier (e.g., one ofmedia asset identifiers 104, 108, and 110) and the characters of thesecond media asset identifier (e.g., one of media asset identifiers 116and 120). The media guidance application may then compare this to athreshold number or percentage of matched characters (e.g., 70%) anddetermine whether the amount or percentage of characters matched betweenthe first media asset identifier and the second media asset identifierexceeds the threshold.

The media guidance application may, in response to determining that thethreshold amount of the characters of the first media asset identifiermatch the characters of the second media asset identifier, retrievemetadata associated with the first media asset identifier and metadataassociated with the second media asset identifier. For example, upondetermining that the threshold amount or percentage of charactersmatched is exceeded by the characters of first (e.g., one of media assetidentifiers 104, 108, and 110) and second media asset identifiers (e.g.,one of media asset identifiers 116 and 120), the media guidanceapplication may retrieve metadata associated with the first and secondmedia asset identifiers. The metadata may be any data relating to themedia asset identifiers, including some or all of the associateddetailed information (e.g., detailed information 106). As an example,the first media asset identifier may be “Star Wars: Episode I” and thesecond media asset identifier may be “Star Wars: First Episode.” Despitethe differences between identifiers (e.g., based on character comparisonas described above), the media guidance application may determine thetwo media asset identifiers match based on metadata (e.g., the actorsand director) matching between the two identifiers since a thresholdnumber of characters match.

The media guidance application may then compare the metadata associatedwith the first media asset identifier and the metadata associated withthe second media asset identifier. For example, the media guidanceapplication may compare a string of characters for the directorassociated with the first media asset identifier (e.g., one of mediaasset identifiers 104, 108, and 110) and the second media assetidentifier (e.g., one of media asset identifiers 116 and 120) in thesame manner as discussed above for comparing characters of the mediaasset identifiers. The media guidance application may then determinewhether the metadata associated with the first media asset identifiercorresponds to the metadata associated with the second media assetidentifier. For example, the media guidance application may determinewhether the metadata corresponds based on whether all, or a thresholdnumber or percentage, of characters of the metadata associated with thefirst (e.g., one of media asset identifiers 104, 108, and 110) andsecond media asset identifier (e.g., one of media asset identifiers 116and 120) are matched. The media guidance application, in response todetermining the metadata associated with the first media assetidentifier matches the metadata associated with the second media assetidentifier, determines the first media asset identifier corresponds tothe second media asset identifier. For example, the media guidanceapplication may determine that since a threshold amount of thecharacters match and that the metadata matches, the media assetidentifiers match (e.g., one of media asset identifiers 104, 108, and110 matches with one of media asset identifiers 116 and 120) and thusthe second media asset identifier is part of the first subset (e.g.,detailed information is already stored locally).

In some embodiments, if either the metadata or threshold amount ofcharacters of the media asset identifiers match, but not both, the mediaguidance application may determine that the media asset identifiers arerelated and a subset of the detailed information between the two mediaasset identifiers corresponds and can be retrieved from local storage,but some detailed information may be retrieved from a remote server(e.g., if the media asset identifiers are different episodes of aseries, the director and actors may be the same but the summary may bedifferent).

Alternatively or additionally, the media guidance application may, inresponse to determining that the characters of the first media assetidentifier do not match the characters of the second media assetidentifier, access a data structure containing indications of whethermedia asset identifiers are associated. For example, the media guidanceapplication may access a data structure containing equivalentidentifiers which may be organized as a table where each entry (e.g.,row) contains identifiers that are associated with the same media asset.The media guidance application may then retrieve an entry in the datastructure for the first media asset identifier (e.g., one of media assetidentifiers 104, 108, and 110). For example, the media guidanceapplication may execute an instruction (e.g., an SQL program scriptutilizing the “Select” command) to retrieve, from an entry for a firstmedia asset identifier, all other associated media asset identifiers(e.g., from fields associated with the entry).

The media guidance application may then determine, based on data in theentry identifying the second media asset identifier, that the secondmedia asset identifier is associated with the first media assetidentifier. For example, the media guidance application may retrieve,from fields associated with an entry for the media asset identifier“Star Wars: Episode I,” media asset identifiers “Star Wars: FirstEpisode,” and “Star Wars: Ep. 1” indicated as equivalent media assetidentifiers. Based on comparing (e.g., by character comparison asdescribed above) the second media asset identifier (e.g., one of mediaasset identifiers 116 and 120) to the retrieved equivalent identifiers,the media guidance application can determine whether they areassociated. The media guidance application may, in response todetermining the first media asset identifier is associated with thesecond media asset identifier, determine a subset of the detailedinformation (e.g., detailed information 118) for the second media assetidentifier that matches the first media asset identifier. As describedfurther below, when two media asset identifiers are related orassociated, but do not exactly match, some detailed information may becommon to both identifiers and some may not. For example, the mediaguidance application may store a list of detailed information that iscommon between media asset identifiers determined to be related orassociated, such as actors. The media guidance application may retrievethe subset of detailed information from local storage.

In some embodiments, the media guidance application may determine thedetailed info Illation for the second media asset identifier notretrieved from the local storage device. For example, as describedabove, the media guidance application may determine that a subset ofdetailed information (e.g., actor names) is common to both the first(e.g., one of media asset identifiers 104, 108, and 110) and secondmedia asset identifiers (e.g., one of media asset identifiers 116 and120). However, some detailed information (e.g., a summary) may not becommon to both. In this situation, the media guidance applicationretrieves the detailed information for the second media asset identifiernot retrieved from the local storage device from the remote server. Themedia guidance application thus can generate a full set of detailedinformation for the second media asset identifier for display withouthaving to retrieve all of the information (which may causedelays/increase network traffic) from the remote server.

In some embodiments, the media guidance application may determine that afirst media asset identifier of the first plurality of media assetidentifiers is related, but not identical, to a second media assetidentifier of the second plurality of media asset identifiers. Forexample, the media guidance application may determine, as describedabove, that the first (e.g., one of media asset identifiers 104, 108,and 110) and second media asset identifiers (e.g., one of media assetidentifiers 116 and 120) are not identical because of a difference intheir characters. However, the media guidance application may determinethat the two media asset identifiers are related or associated (e.g.,based on a threshold number of characters matching, metadatacorresponding, and/or a stored indication the two identifiers arerelated). For example, the first media asset identifier may be for “StarWars: Episode II” and the second media asset identifier may be for “StarWars: Episode III.” While not identical, the media guidance applicationmay determine that since the two media asset identifiers are relatedbased on an indication that they are part of a series, some of thedetailed information may be relevant. The media guidance application maythen determine to retrieve a subset of the detailed information (e.g.,detailed information 106) from the first media asset identifier todisplay with the second media asset identifier (e.g., detailedinformation 118) instead of transmitting a request to the remote serverfor the detailed information. As a specific example, the media guidanceapplication may determine from a data structure that media assetidentifiers that are part of a series often have the same actors,directors, and genres but not the same title or summary. Accordingly,the media guidance application may retrieve the actor, director andgenre for “Star Wars: Episode II” and generate them for display with theidentifier for “Star Wars: Episode III,” thus saving a transaction withthe remote server. In some embodiments, the media guidance applicationstores whether to request detailed information for related media assetsas a user configurable option (e.g., via a button in a user interface)that can be toggled on or off.

The media guidance application may determine a second subset of mediaasset identifiers, the second subset including each media assetidentifier of the second plurality of media asset identifiers where datain the first respective entry does not match data in the secondrespective entry. For example, the media guidance application mayexecute the program script described above for comparing media assetidentifiers in the first (e.g., one of media asset identifiers 104, 108,and 110) and second (e.g., one of media asset identifiers 116 and 120)plurality of media asset identifiers and sort any media assetidentifiers unique to the second plurality of media asset identifiers(e.g., media asset identifiers 120) into a list or other data structure(e.g., the second subset). For example, the media guidance applicationmay, for each media asset identifier of the second plurality, retrievedata to compare from every media asset identifier of the firstplurality. If none of the data compared (e.g., characters of theidentifiers) match, then the media guidance application may execute aninstruction to write an identifier of the media asset identifier forwhich none of the data matches to a list or other data structuredefining the second subset (e.g., where detailed information has notalready been retrieved from the remote server).

The media guidance application may then retrieve detailed informationfor each media asset identifier in the first subset of media assetidentifiers from memory. For example, the media guidance application hasalready retrieved the detailed information for each media assetidentifier in the first subset (e.g., containing media asset identifierscommon to both first group of media asset identifiers 102 and secondgroup of media asset identifiers 114) from the remote server (e.g.,media guidance data source). The media guidance application may storethe detailed information (e.g., detailed information 106) in volatilememory (e.g., DRAM or SRAM) due to not having enough non-volatile memoryavailable to store the detailed information permanently. Since thedetailed information has already been retrieved for each media asset inthe second subset (e.g., since media asset identifier 104 corresponds tomedia asset identifier 116), the media guidance application retrievesthe detailed information (e.g., detailed information 106) from thecorresponding blocks of memory where it is stored instead oftransmitting a request for the detailed information to the remoteserver, minimizing transactions with the remote server and alsomaximizing the speed at which the second group of media assetidentifiers can be loaded.

The media guidance application may then retrieve detailed informationfor each media asset identifier in the second subset of media assetidentifiers from a remote server. For example, for media assetidentifiers where the detailed information has not been receivedpreviously (e.g., media asset identifiers 120), the media guidanceapplication retrieves the detailed information from the remote server.For example, as described above for retrieving detailed information forthe first plurality of media assets, the media guidance applicationtransmits a data packet to a remote server containing each media assetidentifier in the second subset. For example, the media guidanceapplication may transmit the data packet including a single media assetidentifier or a list or other suitable data structure of media assetidentifiers. The media guidance application may then receive, from theremote server, the detailed information for each media asset identifierin the second subset.

In some embodiments, the media guidance application may determine that athird plurality of media asset identifiers are stored on the localstorage device. For example, the media guidance application may haveretrieved detailed information about a third group of media assets andmay determine whether any detailed information retrieved for the thirdplurality of media asset identifiers overlaps with the second pluralityof media asset identifiers (e.g., media asset identifiers 116 and 120).The media guidance application may then determine a third subset ofmedia asset identifiers that are in both the second plurality of mediaasset identifiers and the third plurality of media asset identifiers. Asdescribed above when determining the first subset, the media guidanceapplication may determine whether each media asset identifier of thesecond plurality of media asset identifiers matches one of the mediaasset identifiers of the third plurality and store an indication on alist or other data structure for each media asset identifier thatmatches. The media guidance application may then retrieve detailedinformation for each media asset identifier in the third subset of mediaasset identifiers from the local storage device. For example, asdescribed above for the first subset, the media guidance application mayretrieve detailed information from the local storage device since it hasalready been retrieved when the third plurality of media assetidentifiers were previously displayed.

In some embodiments, the media guidance application retrieves atimestamp for detailed information for a first media asset identifier inthe first subset stored on the local storage device. For example, themedia guidance application may store a timestamp (e.g., the date andtime) that detailed information (e.g., detailed information 106) for amedia asset identifier (e.g., media asset identifier 104) was retrieved.The media guidance application may maintain a data structure withtimestamps of when detailed descriptions were retrieved, or thetimestamps may be stored with the detailed information (e.g., as a fieldin a table containing the detailed information). The media guidanceapplication may determine, by subtracting the timestamp from the currenttime, whether the detailed information for the first media assetidentifier exceeds a threshold amount of time stored. For example, themedia guidance application may determine that the current time is 15:31on 05-31-2016 (e.g., May 31, 2016) and the detailed information wasretrieved at 10:31 on 05-24-2016. The media guidance application maydetermine the amount of time elapsed since retrieval of the detailedinformation by subtracting the individual values (e.g., 05 from 05, 24from 31, etc.). As an example, the media guidance application maycalculate that the time elapsed is five hours past one week (e.g., sevendays and five hours). The media guidance application may then comparethis value to a threshold value (e.g., five days) to determine whetherthe elapsed time exceeds the threshold time.

The media guidance application may then, in response to determining thatthe detailed information for the first media asset identifier exceedsthe threshold amount of time stored, delete the detailed information forthe first media asset identifier stored on the local storage device. Forexample, the media guidance application may delete the detailedinformation (e.g., detailed information 106) from the local storagedevice as opposed to retrieving it if the elapsed time is greater thanthe threshold time. The media guidance application may then retrieve newdetailed information (e.g., to replace detailed information 106) for thefirst media asset identifier (e.g., media asset identifier 104) from theremote server. For example, as described above, the media guidanceapplication may transmit a request for detailed information relating tothe media asset identifier to a remote server. The media guidanceapplication may then receive detailed information associated with themedia asset identifier (e.g., in a data packet) from the remote server.The media guidance application may then store the new detailedinformation for the first media identifier on the local storage device.

In some embodiments, the media guidance application may generate fordisplay a plurality of options for types of detailed information toretrieve. For example, the media guidance application may generate auser interface including a plurality of options to customize what typesof information is retrieved from a remote server. For example, theoptions may be for types of detailed information (e.g., a subset ofdetailed information 106) such as an option to not retrieve detailedinformation of type “actor,” “director,” “summary” or any other subsetof the detailed information. The media guidance application may thenreceive a user input of a first option to not retrieve a first type ofdetailed information if it is not stored in the local storage device.For example, the media guidance application may receive a user input(e.g., via a user input interface) of an option to not retrieve detailedinformation for type “actor.” The media guidance application may, inresponse to receiving the user input, store an indication in the localstorage device to only retrieve the first type of detailed informationif it is stored in the local storage device. For example, the mediaguidance application may store (e.g., in a data structure) an indicationthat unless “actor” information is stored locally, it is not to beretrieved (e.g., not retrieved from a remote server). In this way, themedia guidance application allows the user to customize the informationthat is retrieved and stored and more efficiently manage storage on astorage device with limited capacity.

The amount of content available to users in any given content deliverysystem can be substantial. Consequently, many users desire a form ofmedia guidance through an interface that allows users to efficientlynavigate content selections and easily identify content that they maydesire. An application that provides such guidance is referred to hereinas an interactive media guidance application or, sometimes, a mediaguidance application or a guidance application.

Interactive media guidance applications may take various forms dependingon the content for which they provide guidance. One typical type ofmedia guidance application is an interactive television program guide.Interactive television program guides (sometimes referred to aselectronic program guides) are well-known guidance applications that,among other things, allow users to navigate among and locate many typesof content or media assets. Interactive media guidance applications maygenerate graphical user interface screens that enable a user to navigateamong, locate and select content. As referred to herein, the terms“media asset” and “content” should be understood to mean anelectronically consumable user asset, such as television programming, aswell as pay-per-view programs, on-demand programs (as in video-on-demand(VOD) systems), Internet content (e.g., streaming content, downloadablecontent, Webcasts, etc.), video clips, audio, content information,pictures, rotating images, documents, playlists, websites, articles,books, electronic books, blogs, chat sessions, social media,applications, games, and/or any other media or multimedia and/orcombination of the same. Guidance applications also allow users tonavigate among and locate content. As referred to herein, the term“multimedia” should be understood to mean content that utilizes at leasttwo different content forms described above, for example, text, audio,images, video, or interactivity content forms. Content may be recorded,played, displayed or accessed by user equipment devices, but can also bepart of a live performance.

The media guidance application and/or any instructions for performingany of the embodiments discussed herein may be encoded on computerreadable media. Computer readable media includes any media capable ofstoring data. The computer readable media may be transitory, including,but not limited to, propagating electrical or electromagnetic signals,or may be non-transitory including, but not limited to, volatile andnon-volatile computer memory or storage devices such as a hard disk,floppy disk, USB drive, DVD, CD, media cards, register memory, processorcaches, Random Access Memory (“RAM”), etc.

With the advent of the Internet, mobile computing, and high-speedwireless networks, users are accessing media on user equipment deviceson which they traditionally did not. As referred to herein, the phrase“user equipment device,” “user equipment,” “user device,” “electronicdevice,” “electronic equipment,” “media equipment device,” or “mediadevice” should be understood to mean any device for accessing thecontent described above, such as a television, a Smart TV, a set-topbox, an integrated receiver decoder (IRD) for handling satellitetelevision, a digital storage device, a digital media receiver (DMR), adigital media adapter (DMA), a streaming media device, a DVD player, aDVD recorder, a connected DVD, a local media server, a BLU-RAY player, aBLU-RAY recorder, a personal computer (PC), a laptop computer, a tabletcomputer, a WebTV box, a personal computer television (PC/TV), a PCmedia server, a PC media center, a hand-held computer, a stationarytelephone, a personal digital assistant (PDA), a mobile telephone, aportable video player, a portable music player, a portable gamingmachine, a smart phone, or any other television equipment, computingequipment, or wireless device, and/or combination of the same. In someembodiments, the user equipment device may have a front facing screenand a rear facing screen, multiple front screens, or multiple angledscreens. In some embodiments, the user equipment device may have a frontfacing camera and/or a rear facing camera. On these user equipmentdevices, users may be able to navigate among and locate the same contentavailable through a television. Consequently, media guidance may beavailable on these devices, as well. The guidance provided may be forcontent available only through a television, for content available onlythrough one or more of other types of user equipment devices, or forcontent available both through a television and one or more of the othertypes of user equipment devices. The media guidance applications may beprovided as on-line applications (i.e., provided on a web-site), or asstand-alone applications or clients on user equipment devices. Variousdevices and platforms that may implement media guidance applications aredescribed in more detail below.

One of the functions of the media guidance application is to providemedia guidance data to users. As referred to herein, the phrase “mediaguidance data” or “guidance data” should be understood to mean any datarelated to content or data used in operating the guidance application.For example, the guidance data may include program information, guidanceapplication settings, user preferences, user profile information, medialistings, media-related information (e.g., broadcast times, broadcastchannels, titles, descriptions, ratings information (e.g., parentalcontrol ratings, critic's ratings, etc.), genre or category information,actor information, logo data for broadcasters' or providers' logos,etc.), media format (e.g., standard definition, high definition, 3D,etc.), on-demand information, blogs, websites, and any other type ofguidance data that is helpful for a user to navigate among and locatedesired content selections.

FIGS. 2-3 show illustrative display screens that may be used to providemedia guidance data. The display screens shown in FIGS. 2-3 may beimplemented on any suitable user equipment device or platform. While thedisplays of FIGS. 2-3 are illustrated as full screen displays, they mayalso be fully or partially overlaid over content being displayed. A usermay indicate a desire to access content information by selecting aselectable option provided in a display screen (e.g., a menu option, alistings option, an icon, a hyperlink, etc.) or pressing a dedicatedbutton (e.g., a GUIDE button) on a remote control or other user inputinterface or device. In response to the user's indication, the mediaguidance application may provide a display screen with media guidancedata organized in one of several ways, such as by time and channel in agrid, by time, by channel, by source, by content type, by category(e.g., movies, sports, news, children, or other categories ofprogramming), or other predefined, user-defined, or other organizationcriteria.

FIG. 2 shows an illustrative grid of a program listings display 200arranged by time and channel that also enables access to different typesof content in a single display. Display 200 may include grid 202 with:(1) a column of channel/content type identifiers 204, where eachchannel/content type identifier (which is a cell in the column)identifies a different channel or content type available; and (2) a rowof time identifiers 206, where each time identifier (which is a cell inthe row) identifies a time block of programming. Grid 202 also includescells of program listings, such as program listing 208, where eachlisting provides the title of the program provided on the listing'sassociated channel and time. With a user input device, a user can selectprogram listings by moving highlight region 210. Information relating tothe program listing selected by highlight region 210 may be provided inprogram information region 212. Region 212 may include, for example, theprogram title, the program description, the time the program is provided(if applicable), the channel the program is on (if applicable), theprogram's rating, and other desired information.

In addition to providing access to linear programming (e.g., contentthat is scheduled to be transmitted to a plurality of user equipmentdevices at a predetermined time and is provided according to aschedule), the media guidance application also provides access tonon-linear programming (e.g., content accessible to a user equipmentdevice at any time and is not provided according to a schedule).Non-linear programming may include content from different contentsources including on-demand content (e.g., VOD), Internet content (e.g.,streaming media, downloadable media, etc.), locally stored content(e.g., content stored on any user equipment device described above orother storage device), or other time-independent content. On-demandcontent may include movies or any other content provided by a particularcontent provider (e.g., HBO On Demand providing “The Sopranos” and “CurbYour Enthusiasm”). HBO ON DEMAND is a service mark owned by Time WarnerCompany L.P. et al. and THE SOPRANOS and CURB YOUR ENTHUSIASM aretrademarks owned by the Home Box Office, Inc. Internet content mayinclude web events, such as a chat session or Webcast, or contentavailable on-demand as streaming content or downloadable content throughan Internet web site or other Internet access (e.g. FTP).

Grid 202 may provide media guidance data for non-linear programmingincluding on-demand listing 214, recorded content listing 216, andInternet content listing 218. A display combining media guidance datafor content from different types of content sources is sometimesreferred to as a “mixed-media” display. Various permutations of thetypes of media guidance data that may be displayed that are differentthan display 200 may be based on user selection or guidance applicationdefinition (e.g., a display of only recorded and broadcast listings,only on-demand and broadcast listings, etc.). As illustrated, listings214, 216, and 218 are shown as spanning the entire time block displayedin grid 202 to indicate that selection of these listings may provideaccess to a display dedicated to on-demand listings, recorded listings,or Internet listings, respectively. In some embodiments, listings forthese content types may be included directly in grid 202. Additionalmedia guidance data may be displayed in response to the user selectingone of the navigational icons 220. (Pressing an arrow key on a userinput device may affect the display in a similar manner as selectingnavigational icons 220.)

Display 200 may also include video region 222, and options region 226.Video region 222 may allow the user to view and/or preview programs thatare currently available, will be available, or were available to theuser. The content of video region 222 may correspond to, or beindependent from, one of the listings displayed in grid 202. Griddisplays including a video region are sometimes referred to aspicture-in-guide (PIG) displays. PIG displays and their functionalitiesare described in greater detail in Satterfield et al. U.S. Pat. No.6,564,378, issued May 13, 2003 and Yuen et al. U.S. Pat. No. 6,239,794,issued May 29, 2001, which are hereby incorporated by reference hereinin their entireties. PIG displays may be included in other mediaguidance application display screens of the embodiments describedherein.

Options region 226 may allow the user to access different types ofcontent, media guidance application displays, and/or media guidanceapplication features. Options region 226 may be part of display 200 (andother display screens described herein), or may be invoked by a user byselecting an on-screen option or pressing a dedicated or assignablebutton on a user input device. The selectable options within optionsregion 226 may concern features related to program listings in grid 202or may include options available from a main menu display. Featuresrelated to program listings may include searching for other air times orways of receiving a program, recording a program, enabling seriesrecording of a program, setting program and/or channel as a favorite,purchasing a program, or other features. Options available from a mainmenu display may include search options, VOD options, parental controloptions, Internet options, cloud-based options, device synchronizationoptions, second screen device options, options to access various typesof media guidance data displays, options to subscribe to a premiumservice, options to edit a user's profile, options to access a browseoverlay, or other options.

The media guidance application may be personalized based on a user'spreferences. A personalized media guidance application allows a user tocustomize displays and features to create a personalized “experience”with the media guidance application. This personalized experience may becreated by allowing a user to input these customizations and/or by themedia guidance application monitoring user activity to determine varioususer preferences. Users may access their personalized guidanceapplication by logging in or otherwise identifying themselves to theguidance application. Customization of the media guidance applicationmay be made in accordance with a user profile. The customizations mayinclude varying presentation schemes (e.g., color scheme of displays,font size of text, etc.), aspects of content listings displayed (e.g.,only HDTV or only 3D programming, user-specified broadcast channelsbased on favorite channel selections, re-ordering the display ofchannels, recommended content, etc.), desired recording features (e.g.,recording or series recordings for particular users, recording quality,etc.), parental control settings, customized presentation of Internetcontent (e.g., presentation of social media content, e-mail,electronically delivered articles, etc.) and other desiredcustomizations.

The media guidance application may allow a user to provide user profileinformation or may automatically compile user profile information. Themedia guidance application may, for example, monitor the content theuser accesses and/or other interactions the user may have with theguidance application. Additionally, the media guidance application mayobtain all or part of other user profiles that are related to aparticular user (e.g., from other web sites on the Internet the useraccesses, such as www.allrovi.com, from other media guidanceapplications the user accesses, from other interactive applications theuser accesses, from another user equipment device of the user, etc.),and/or obtain information about the user from other sources that themedia guidance application may access. As a result, a user can beprovided with a unified guidance application experience across theuser's different user equipment devices. This type of user experience isdescribed in greater detail below in connection with FIG. 5. Additionalpersonalized media guidance application features are described ingreater detail in Ellis et al., U.S. Patent Application Publication No.2005/0251827, filed Jul. 11, 2005, Boyer et al., U.S. Pat. No.7,165,098, issued Jan. 16, 2007, and Ellis et al., U.S. PatentApplication Publication No. 2002/0174430, filed Feb. 21, 2002, which arehereby incorporated by reference herein in their entireties.

Another display arrangement for providing media guidance is shown inFIG. 3. Video mosaic display 300 includes selectable options 302 forcontent information organized based on content type, genre, and/or otherorganization criteria. In display 300, television listings option 304 isselected, thus providing listings 306, 308, 310, and 312 as broadcastprogram listings. In display 300 the listings may provide graphicalimages including cover art, still images from the content, video clippreviews, live video from the content, or other types of content thatindicate to a user the content being described by the media guidancedata in the listing. Each of the graphical listings may also beaccompanied by text to provide further information about the contentassociated with the listing. For example, listing 308 may include morethan one portion, including media portion 314 and text portion 316.Media portion 314 and/or text portion 316 may be selectable to viewcontent in full-screen or to view information related to the contentdisplayed in media portion 314 (e.g., to view listings for the channelthat the video is displayed on).

The listings in display 300 are of different sizes (i.e., listing 306 islarger than listings 308, 310, and 312), but if desired, all thelistings may be the same size. Listings may be of different sizes orgraphically accentuated to indicate degrees of interest to the user orto emphasize certain content, as desired by the content provider orbased on user preferences. Various systems and methods for graphicallyaccentuating content listings are discussed in, for example, Yates, U.S.Patent Application Publication No. 2010/0153885, filed Nov. 12, 2009,which is hereby incorporated by reference herein in its entirety.

Users may access content and the media guidance application (and itsdisplay screens described above and below) from one or more of theiruser equipment devices. FIG. 4 shows a generalized embodiment ofillustrative user equipment device 400. More specific implementations ofuser equipment devices are discussed below in connection with FIG. 5.User equipment device 400 may receive content and data via input/output(hereinafter “I/O”) path 402. I/O path 402 may provide content (e.g.,broadcast programming, on-demand programming, Internet content, contentavailable over a local area network (LAN) or wide area network (WAN),and/or other content) and data to control circuitry 404, which includesprocessing circuitry 406 and storage 408. Control circuitry 404 may beused to send and receive commands, requests, and other suitable datausing I/O path 402. I/O path 402 may connect control circuitry 404 (andspecifically processing circuitry 406) to one or more communicationspaths (described below). I/O functions may be provided by one or more ofthese communications paths, but are shown as a single path in FIG. 4 toavoid overcomplicating the drawing.

Control circuitry 404 may be based on any suitable processing circuitrysuch as processing circuitry 406. As referred to herein, processingcircuitry should be understood to mean circuitry based on one or moremicroprocessors, microcontrollers, digital signal processors,programmable logic devices, field-programmable gate arrays (FPGAs),application-specific integrated circuits (ASICs), etc., and may includea multi-core processor (e.g., dual-core, quad-core, hexa-core, or anysuitable number of cores) or supercomputer. In some embodiments,processing circuitry may be distributed across multiple separateprocessors or processing units, for example, multiple of the same typeof processing units (e.g., two Intel Core i7 processors) or multipledifferent processors (e.g., an Intel Core i5 processor and an Intel Corei7 processor). In some embodiments, control circuitry 404 executesinstructions for a media guidance application stored in memory (i.e.,storage 408). Specifically, control circuitry 404 may be instructed bythe media guidance application to perform the functions discussed aboveand below. For example, the media guidance application may provideinstructions to control circuitry 404 to generate the media guidancedisplays. In some implementations, any action performed by controlcircuitry 404 may be based on instructions received from the mediaguidance application.

In client-server based embodiments, control circuitry 404 may includecommunications circuitry suitable for communicating with a guidanceapplication server or other networks or servers. The instructions forcarrying out the above mentioned functionality may be stored on theguidance application server. Communications circuitry may include acable modem, an integrated services digital network (ISDN) modem, adigital subscriber line (DSL) modem, a telephone modem, Ethernet card,or a wireless modem for communications with other equipment, or anyother suitable communications circuitry. Such communications may involvethe Internet or any other suitable communications networks or paths(which is described in more detail in connection with FIG. 5). Inaddition, communications circuitry may include circuitry that enablespeer-to-peer communication of user equipment devices, or communicationof user equipment devices in locations remote from each other (describedin more detail below).

Memory may be an electronic storage device provided as storage 408 thatis part of control circuitry 404. As referred to herein, the phrase“electronic storage device” or “storage device” should be understood tomean any device for storing electronic data, computer software, orfirmware, such as random-access memory, read-only memory, hard drives,optical drives, digital video disc (DVD) recorders, compact disc (CD)recorders, BLU-RAY disc (BD) recorders, BLU-RAY 3D disc recorders,digital video recorders (DVR, sometimes called a personal videorecorder, or PVR), solid state devices, quantum storage devices, gamingconsoles, gaming media, or any other suitable fixed or removable storagedevices, and/or any combination of the same. Storage 408 may be used tostore various types of content described herein as well as mediaguidance data described above. Nonvolatile memory may also be used(e.g., to launch a boot-up routine and other instructions). Cloud-basedstorage, described in relation to FIG. 5, may be used to supplementstorage 408 or instead of storage 408.

Control circuitry 404 may include video generating circuitry and tuningcircuitry, such as one or more analog tuners, one or more MPEG-2decoders or other digital decoding circuitry, high-definition tuners, orany other suitable tuning or video circuits or combinations of suchcircuits. Encoding circuitry (e.g., for converting over-the-air, analog,or digital signals to MPEG signals for storage) may also be provided.Control circuitry 404 may also include scaler circuitry for upconvertingand downconverting content into the preferred output format of the userequipment 400. Circuitry 404 may also include digital-to-analogconverter circuitry and analog-to-digital converter circuitry forconverting between digital and analog signals. The tuning and encodingcircuitry may be used by the user equipment device to receive and todisplay, to play, or to record content. The tuning and encodingcircuitry may also be used to receive guidance data. The circuitrydescribed herein, including for example, the tuning, video generating,encoding, decoding, encrypting, decrypting, scaler, and analog/digitalcircuitry, may be implemented using software running on one or moregeneral purpose or specialized processors. Multiple tuners may beprovided to handle simultaneous tuning functions (e.g., watch and recordfunctions, picture-in-picture (PIP) functions, multiple-tuner recording,etc.). If storage 408 is provided as a separate device from userequipment 400, the tuning and encoding circuitry (including multipletuners) may be associated with storage 408.

A user may send instructions to control circuitry 404 using user inputinterface 410. User input interface 410 may be any suitable userinterface, such as a remote control, mouse, trackball, keypad, keyboard,touch screen, touchpad, stylus input, joystick, voice recognitioninterface, or other user input interfaces. Display 412 may be providedas a stand-alone device or integrated with other elements of userequipment device 400. For example, display 412 may be a touchscreen ortouch-sensitive display. In such circumstances, user input interface 410may be integrated with or combined with display 412. Display 412 may beone or more of a monitor, a television, a liquid crystal display (LCD)for a mobile device, amorphous silicon display, low temperature polysilicon display, electronic ink display, electrophoretic display, activematrix display, electro-wetting display, electrofluidic display, cathoderay tube display, light-emitting diode display, electroluminescentdisplay, plasma display panel, high-performance addressing display,thin-film transistor display, organic light-emitting diode display,surface-conduction electron-emitter display (SED), laser television,carbon nanotubes, quantum dot display, interferometric modulatordisplay, or any other suitable equipment for displaying visual images.In some embodiments, display 412 may be HDTV-capable. In someembodiments, display 412 may be a 3D display, and the interactive mediaguidance application and any suitable content may be displayed in 3D. Avideo card or graphics card may generate the output to the display 412.The video card may offer various functions such as accelerated renderingof 3D scenes and 2D graphics, MPEG-2/MPEG-4 decoding, TV output, or theability to connect multiple monitors. The video card may be anyprocessing circuitry described above in relation to control circuitry404. The video card may be integrated with the control circuitry 404.Speakers 414 may be provided as integrated with other elements of userequipment device 400 or may be stand-alone units. The audio component ofvideos and other content displayed on display 412 may be played throughspeakers 414. In some embodiments, the audio may be distributed to areceiver (not shown), which processes and outputs the audio via speakers414.

The guidance application may be implemented using any suitablearchitecture. For example, it may be a stand-alone applicationwholly-implemented on user equipment device 400. In such an approach,instructions of the application are stored locally (e.g., in storage408), and data for use by the application is downloaded on a periodicbasis (e.g., from an out-of-band feed, from an Internet resource, orusing another suitable approach). Control circuitry 404 may retrieveinstructions of the application from storage 408 and process theinstructions to generate any of the displays discussed herein. Based onthe processed instructions, control circuitry 404 may determine whataction to perform when input is received from input interface 410. Forexample, movement of a cursor on a display up/down may be indicated bythe processed instructions when input interface 410 indicates that anup/down button was selected.

In some embodiments, the media guidance application is a client-serverbased application. Data for use by a thick or thin client implemented onuser equipment device 400 is retrieved on-demand by issuing requests toa server remote to the user equipment device 400. In one example of aclient-server based guidance application, control circuitry 404 runs aweb browser that interprets web pages provided by a remote server. Forexample, the remote server may store the instructions for theapplication in a storage device. The remote server may process thestored instructions using circuitry (e.g., control circuitry 404) andgenerate the displays discussed above and below. The client device mayreceive the displays generated by the remote server and may display thecontent of the displays locally on equipment device 400. This way, theprocessing of the instructions is performed remotely by the server whilethe resulting displays are provided locally on equipment device 400.Equipment device 400 may receive inputs from the user via inputinterface 410 and transmit those inputs to the remote server forprocessing and generating the corresponding displays. For example,equipment device 400 may transmit a communication to the remote serverindicating that an up/down button was selected via input interface 410.The remote server may process instructions in accordance with that inputand generate a display of the application corresponding to the input(e.g., a display that moves a cursor up/down). The generated display isthen transmitted to equipment device 400 for presentation to the user.

In some embodiments, the media guidance application is downloaded andinterpreted or otherwise run by an interpreter or virtual machine (runby control circuitry 404). In some embodiments, the guidance applicationmay be encoded in the ETV Binary Interchange Format (EBIF), received bycontrol circuitry 404 as part of a suitable feed, and interpreted by auser agent running on control circuitry 404. For example, the guidanceapplication may be an EBIF application. In some embodiments, theguidance application may be defined by a series of JAVA-based files thatare received and run by a local virtual machine or other suitablemiddleware executed by control circuitry 404. In some of suchembodiments (e.g., those employing MPEG-2 or other digital mediaencoding schemes), the guidance application may be, for example, encodedand transmitted in an MPEG-2 object carousel with the MPEG audio andvideo packets of a program.

User equipment device 400 of FIG. 4 can be implemented in system 500 ofFIG. 5 as user television equipment 502, user computer equipment 504,wireless user communications device 506, or any other type of userequipment suitable for accessing content, such as a non-portable gamingmachine. For simplicity, these devices may be referred to hereincollectively as user equipment or user equipment devices, and may besubstantially similar to user equipment devices described above. Userequipment devices, on which a media guidance application may beimplemented, may function as a standalone device or may be part of anetwork of devices. Various network configurations of devices may beimplemented and are discussed in more detail below.

A user equipment device utilizing at least some of the system featuresdescribed above in connection with FIG. 4 may not be classified solelyas user television equipment 502, user computer equipment 504, or awireless user communications device 506. For example, user televisionequipment 502 may, like some user computer equipment 504, beInternet-enabled allowing for access to Internet content, while usercomputer equipment 504 may, like some television equipment 502, includea tuner allowing for access to television programming. The mediaguidance application may have the same layout on various different typesof user equipment or may be tailored to the display capabilities of theuser equipment. For example, on user computer equipment 504, theguidance application may be provided as a web site accessed by a webbrowser. In another example, the guidance application may be scaled downfor wireless user communications devices 506.

In system 500, there is typically more than one of each type of userequipment device but only one of each is shown in FIG. 5 to avoidovercomplicating the drawing. In addition, each user may utilize morethan one type of user equipment device and also more than one of eachtype of user equipment device.

In some embodiments, a user equipment device (e.g., user televisionequipment 502, user computer equipment 504, wireless user communicationsdevice 506) may be referred to as a “second screen device.” For example,a second screen device may supplement content presented on a first userequipment device. The content presented on the second screen device maybe any suitable content that supplements the content presented on thefirst device. In some embodiments, the second screen device provides aninterface for adjusting settings and display preferences of the firstdevice. In some embodiments, the second screen device is configured forinteracting with other second screen devices or for interacting with asocial network. The second screen device can be located in the same roomas the first device, a different room from the first device but in thesame house or building, or in a different building from the firstdevice.

The user may also set various settings to maintain consistent mediaguidance application settings across in-home devices and remote devices.Settings include those described herein, as well as channel and programfavorites, programming preferences that the guidance applicationutilizes to make programming recommendations, display preferences, andother desirable guidance settings. For example, if a user sets a channelas a favorite on, for example, the web site www.allrovi.com on theirpersonal computer at their office, the same channel would appear as afavorite on the user's in-home devices (e.g., user television equipmentand user computer equipment) as well as the user's mobile devices, ifdesired. Therefore, changes made on one user equipment device can changethe guidance experience on another user equipment device, regardless ofwhether they are the same or a different type of user equipment device.In addition, the changes made may be based on settings input by a user,as well as user activity monitored by the guidance application.

The user equipment devices may be coupled to communications network 514.Namely, user television equipment 502, user computer equipment 504, andwireless user communications device 506 are coupled to communicationsnetwork 514 via communications paths 508, 510, and 512, respectively.Communications network 514 may be one or more networks including theInternet, a mobile phone network, mobile voice or data network (e.g., a4G or LTE network), cable network, public switched telephone network, orother types of communications network or combinations of communicationsnetworks. Paths 508, 510, and 512 may separately or together include oneor more communications paths, such as, a satellite path, a fiber-opticpath, a cable path, a path that supports Internet communications (e.g.,IPTV), free-space connections (e.g., for broadcast or other wirelesssignals), or any other suitable wired or wireless communications path orcombination of such paths. Path 512 is drawn with dotted lines toindicate that in the exemplary embodiment shown in FIG. 5 it is awireless path and paths 508 and 510 are drawn as solid lines to indicatethey are wired paths (although these paths may be wireless paths, ifdesired). Communications with the user equipment devices may be providedby one or more of these communications paths, but are shown as a singlepath in FIG. 5 to avoid overcomplicating the drawing.

Although communications paths are not drawn between user equipmentdevices, these devices may communicate directly with each other viacommunication paths, such as those described above in connection withpaths 508, 510, and 512, as well as other short-range point-to-pointcommunication paths, such as USB cables, IEEE 1394 cables, wirelesspaths (e.g., Bluetooth, infrared, IEEE 802-11x, etc.), or othershort-range communication via wired or wireless paths. BLUETOOTH is acertification mark owned by Bluetooth SIG, INC. The user equipmentdevices may also communicate with each other directly through anindirect path via communications network 514.

System 500 includes content source 516 and media guidance data source518 coupled to communications network 514 via communication paths 520and 522, respectively. Paths 520 and 522 may include any of thecommunication paths described above in connection with paths 508, 510,and 512. Communications with the content source 516 and media guidancedata source 518 may be exchanged over one or more communications paths,but are shown as a single path in FIG. 5 to avoid overcomplicating thedrawing. In addition, there may be more than one of each of contentsource 516 and media guidance data source 518, but only one of each isshown in FIG. 5 to avoid overcomplicating the drawing. (The differenttypes of each of these sources are discussed below.) If desired, contentsource 516 and media guidance data source 518 may be integrated as onesource device. Although communications between sources 516 and 518 withuser equipment devices 502, 504, and 506 are shown as throughcommunications network 514, in some embodiments, sources 516 and 518 maycommunicate directly with user equipment devices 502, 504, and 506 viacommunication paths (not shown) such as those described above inconnection with paths 508, 510, and 512.

Content source 516 may include one or more types of content distributionequipment including a television distribution facility, cable systemheadend, satellite distribution facility, programming sources (e.g.,television broadcasters, such as NBC, ABC, HBO, etc.), intermediatedistribution facilities and/or servers, Internet providers, on-demandmedia servers, and other content providers. NBC is a trademark owned bythe National Broadcasting Company, Inc., ABC is a trademark owned by theAmerican Broadcasting Company, Inc., and HBO is a trademark owned by theHome Box Office, Inc. Content source 516 may be the originator ofcontent (e.g., a television broadcaster, a Webcast provider, etc.) ormay not be the originator of content (e.g., an on-demand contentprovider, an Internet provider of content of broadcast programs fordownloading, etc.). Content source 516 may include cable sources,satellite providers, on-demand providers, Internet providers,over-the-top content providers, or other providers of content. Contentsource 516 may also include a remote media server used to storedifferent types of content (including video content selected by a user),in a location remote from any of the user equipment devices. Systems andmethods for remote storage of content, and providing remotely storedcontent to user equipment are discussed in greater detail in connectionwith Ellis et al., U.S. Pat. No. 7,761,892, issued Jul. 20, 2010, whichis hereby incorporated by reference herein in its entirety.

Media guidance data source 518 may provide media guidance data, such asthe media guidance data described above. Media guidance data may beprovided to the user equipment devices using any suitable approach. Insome embodiments, the guidance application may be a stand-aloneinteractive television program guide that receives program guide datavia a data feed (e.g., a continuous feed or trickle feed). Programschedule data and other guidance data may be provided to the userequipment on a television channel sideband, using an in-band digitalsignal, using an out-of-band digital signal, or by any other suitabledata transmission technique. Program schedule data and other mediaguidance data may be provided to user equipment on multiple analog ordigital television channels.

In some embodiments, guidance data from media guidance data source 518may be provided to users' equipment using a client-server approach. Forexample, a user equipment device may pull media guidance data from aserver, or a server may push media guidance data to a user equipmentdevice. In some embodiments, a guidance application client residing onthe user's equipment may initiate sessions with source 518 to obtainguidance data when needed, e.g., when the guidance data is out of dateor when the user equipment device receives a request from the user toreceive data. Media guidance may be provided to the user equipment withany suitable frequency (e.g., continuously, daily, a user-specifiedperiod of time, a system-specified period of time, in response to arequest from user equipment, etc.). Media guidance data source 518 mayprovide user equipment devices 502, 504, and 506 the media guidanceapplication itself or software updates for the media guidanceapplication.

In some embodiments, the media guidance data may include viewer data.For example, the viewer data may include current and/or historical useractivity information (e.g., what content the user typically watches,what times of day the user watches content, whether the user interactswith a social network, at what times the user interacts with a socialnetwork to post information, what types of content the user typicallywatches (e.g., pay TV or free TV), mood, brain activity information,etc.). The media guidance data may also include subscription data. Forexample, the subscription data may identify to which sources or servicesa given user subscribes and/or to which sources or services the givenuser has previously subscribed but later terminated access (e.g.,whether the user subscribes to premium channels, whether the user hasadded a premium level of services, whether the user has increasedInternet speed). In some embodiments, the viewer data and/or thesubscription data may identify patterns of a given user for a period ofmore than one year. The media guidance data may include a model (e.g., asurvivor model) used for generating a score that indicates a likelihooda given user will terminate access to a service/source. For example, themedia guidance application may process the viewer data with thesubscription data using the model to generate a value or score thatindicates a likelihood of whether the given user will terminate accessto a particular service or source. In particular, a higher score mayindicate a higher level of confidence that the user will terminateaccess to a particular service or source. Based on the score, the mediaguidance application may generate promotions that entice the user tokeep the particular service or source indicated by the score as one towhich the user will likely terminate access.

Media guidance applications may be, for example, stand-aloneapplications implemented on user equipment devices. For example, themedia guidance application may be implemented as software or a set ofexecutable instructions which may be stored in storage 408, and executedby control circuitry 404 of a user equipment device 400. In someembodiments, media guidance applications may be client-serverapplications where only a client application resides on the userequipment device, and server application resides on a remote server. Forexample, media guidance applications may be implemented partially as aclient application on control circuitry 404 of user equipment device 400and partially on a remote server as a server application (e.g., mediaguidance data source 518) running on control circuitry of the remoteserver. When executed by control circuitry of the remote server (such asmedia guidance data source 518), the media guidance application mayinstruct the control circuitry to generate the guidance applicationdisplays and transmit the generated displays to the user equipmentdevices. The server application may instruct the control circuitry ofthe media guidance data source 518 to transmit data for storage on theuser equipment. The client application may instruct control circuitry ofthe receiving user equipment to generate the guidance applicationdisplays.

Content and/or media guidance data delivered to user equipment devices502, 504, and 506 may be over-the-top (OTT) content. OTT contentdelivery allows Internet-enabled user devices, including any userequipment device described above, to receive content that is transferredover the Internet, including any content described above, in addition tocontent received over cable or satellite connections. OTT content isdelivered via an Internet connection provided by an Internet serviceprovider (ISP), but a third party distributes the content. The ISP maynot be responsible for the viewing abilities, copyrights, orredistribution of the content, and may only transfer IP packets providedby the OTT content provider. Examples of OTT content providers includeYOUTUBE, NETFLIX, and HULU, which provide audio and video via IPpackets. Youtube is a trademark owned by Google Inc., Netflix is atrademark owned by Netflix Inc., and Hulu is a trademark owned by Hulu,LLC. OTT content providers may additionally or alternatively providemedia guidance data described above. In addition to content and/or mediaguidance data, providers of OTT content can distribute media guidanceapplications (e.g., web-based applications or cloud-based applications),or the content can be displayed by media guidance applications stored onthe user equipment device.

Media guidance system 500 is intended to illustrate a number ofapproaches, or network configurations, by which user equipment devicesand sources of content and guidance data may communicate with each otherfor the purpose of accessing content and providing media guidance. Theembodiments described herein may be applied in any one or a subset ofthese approaches, or in a system employing other approaches fordelivering content and providing media guidance. The following fourapproaches provide specific illustrations of the generalized example ofFIG. 5.

In one approach, user equipment devices may communicate with each otherwithin a home network. User equipment devices can communicate with eachother directly via short-range point-to-point communication schemesdescribed above, via indirect paths through a hub or other similardevice provided on a home network, or via communications network 514.Each of the multiple individuals in a single home may operate differentuser equipment devices on the home network. As a result, it may bedesirable for various media guidance information or settings to becommunicated between the different user equipment devices. For example,it may be desirable for users to maintain consistent media guidanceapplication settings on different user equipment devices within a homenetwork, as described in greater detail in Ellis et al., U.S. PatentPublication No. 2005/0251827, filed Jul. 11, 2005. Different types ofuser equipment devices in a home network may also communicate with eachother to transmit content. For example, a user may transmit content fromuser computer equipment to a portable video player or portable musicplayer.

In a second approach, users may have multiple types of user equipment bywhich they access content and obtain media guidance. For example, someusers may have home networks that are accessed by in-home and mobiledevices. Users may control in-home devices via a media guidanceapplication implemented on a remote device. For example, users mayaccess an online media guidance application on a web site via a personalcomputer at their office, or a mobile device such as a PDA orweb-enabled mobile telephone. The user may set various settings (e.g.,recordings, reminders, or other settings) on the online guidanceapplication to control the user's in-home equipment. The online guidemay control the user's equipment directly, or by communicating with amedia guidance application on the user's in-home equipment. Varioussystems and methods for user equipment devices communicating, where theuser equipment devices are in locations remote from each other, isdiscussed in, for example, Ellis et al., U.S. Pat. No. 8,046,801, issuedOct. 25, 2011, which is hereby incorporated by reference herein in itsentirety.

In a third approach, users of user equipment devices inside and outsidea home can use their media guidance application to communicate directlywith content source 516 to access content. Specifically, within a home,users of user television equipment 502 and user computer equipment 504may access the media guidance application to navigate among and locatedesirable content. Users may also access the media guidance applicationoutside of the home using wireless user communications devices 506 tonavigate among and locate desirable content.

In a fourth approach, user equipment devices may operate in a cloudcomputing environment to access cloud services. In a cloud computingenvironment, various types of computing services for content sharing,storage or distribution (e.g., video sharing sites or social networkingsites) are provided by a collection of network-accessible computing andstorage resources, referred to as “the cloud.” For example, the cloudcan include a collection of server computing devices, which may belocated centrally or at distributed locations, that provide cloud-basedservices to various types of users and devices connected via a networksuch as the Internet via communications network 514. These cloudresources may include one or more content sources 516 and one or moremedia guidance data sources 518. In addition or in the alternative, theremote computing sites may include other user equipment devices, such asuser television equipment 502, user computer equipment 504, and wirelessuser communications device 506. For example, the other user equipmentdevices may provide access to a stored copy of a video or a streamedvideo. In such embodiments, user equipment devices may operate in apeer-to-peer manner without communicating with a central server.

The cloud provides access to services, such as content storage, contentsharing, or social networking services, among other examples, as well asaccess to any content described above, for user equipment devices.Services can be provided in the cloud through cloud computing serviceproviders, or through other providers of online services. For example,the cloud-based services can include a content storage service, acontent sharing site, a social networking site, or other services viawhich user-sourced content is distributed for viewing by others onconnected devices. These cloud-based services may allow a user equipmentdevice to store content to the cloud and to receive content from thecloud rather than storing content locally and accessing locally-storedcontent.

A user may use various content capture devices, such as camcorders,digital cameras with video mode, audio recorders, mobile phones, andhandheld computing devices, to record content. The user can uploadcontent to a content storage service on the cloud either directly, forexample, from user computer equipment 504 or wireless usercommunications device 506 having content capture feature. Alternatively,the user can first transfer the content to a user equipment device, suchas user computer equipment 504. The user equipment device storing thecontent uploads the content to the cloud using a data transmissionservice on communications network 514. In some embodiments, the userequipment device itself is a cloud resource, and other user equipmentdevices can access the content directly from the user equipment deviceon which the user stored the content.

Cloud resources may be accessed by a user equipment device using, forexample, a web browser, a media guidance application, a desktopapplication, a mobile application, and/or any combination of accessapplications of the same. The user equipment device may be a cloudclient that relies on cloud computing for application delivery, or theuser equipment device may have some functionality without access tocloud resources. For example, some applications running on the userequipment device may be cloud applications, i.e., applications deliveredas a service over the Internet, while other applications may be storedand run on the user equipment device. In some embodiments, a user devicemay receive content from multiple cloud resources simultaneously. Forexample, a user device can stream audio from one cloud resource whiledownloading content from a second cloud resource. Or a user device candownload content from multiple cloud resources for more efficientdownloading. In some embodiments, user equipment devices can use cloudresources for processing operations such as the processing operationsperformed by processing circuitry described in relation to FIG. 4.

As referred herein, the term “in response to” refers to initiated as aresult of. For example, a first action being performed in response to asecond action may include interstitial steps between the first actionand the second action. As referred herein, the term “directly inresponse to” refers to caused by. For example, a first action beingperformed directly in response to a second action may not includeinterstitial steps between the first action and the second action.

FIG. 6 is a flowchart of illustrative steps for reducing network trafficwhen retrieving media guidance data, in accordance with some embodimentsof the disclosure. For example, a media guidance applicationimplementing process 600 may be executed by control circuitry 404 (FIG.4). It should be noted that process 600 or any step thereof could beperformed on, or provided by, any of the devices shown in FIGS. 4-5.

Process 600 begins at 602, where the media guidance application receives(e.g., via control circuitry 404) a first user selection to navigate toa first group of media assets comprising a first plurality of mediaasset identifiers. For example, the media guidance application mayreceive (e.g., via control circuitry 404) a user selection (e.g., viauser input interface 410) to display (e.g., on display 412) a group ofmedia asset identifiers. The group of media asset identifiers may be anyset of related or unrelated media assets displayed to a user by themedia guidance application. For example, the group of media assetidentifiers may be a user defined list (e.g., a favorites list), apurchases list, a video-on-demand catalog, a grid-guide showing aplurality of media assets from a plurality of sources, and any othercriteria for grouping a plurality of media assets by the media guidanceapplication.

Process 600 continues to 604, where the media guidance applicationretrieves (e.g., via control circuitry 404), from a database containingmedia asset identifiers associated with groups of media assets, a firstplurality of media asset identifiers corresponding to the first group ofmedia assets. For example, as described further below with respect toFIG. 7, the media guidance application may access (e.g., via controlcircuitry 404) a media guidance database containing media assetidentifiers associated with groups of media assets stored locally (e.g.,in storage 408) or remotely (e.g., at media guidance data source 518 viacommunications network 514). The media guidance application may querythe media guidance database for a specific set of media assetidentifiers associated with the first group of media assets (e.g., avideo-on-demand screen). For example, the media guidance application mayexecute (e.g., via control circuitry 404) a program script utilizing adatabase query language such as SQL to determine whether an entry forthe group of media assets is present in the media guidance database andto retrieve pointers to media asset identifiers stored in fieldsassociated with the entry. The media guidance application may thenretrieve the identifiers from memory (e.g., from a remote server) basedon the pointers.

Process 600 continues to 606, where the media guidance applicationstores (e.g., via control circuitry 404), in a local storage device,respective detailed information for each of the first plurality of mediaasset identifiers retrieved from a remote server. For example, the mediaguidance application may transmit (e.g., via control circuitry 404) arequest or plurality of requests for detailed information for each ofthe media assets identifiers to the remote server (e.g., to mediaguidance data source 518 via communications network 514). As a specificexample, the media guidance application may transmit (e.g., via controlcircuitry 404) a data packet to the remote server containing one or moreidentifiers and may receive the detailed information corresponding tothe one or more identifiers. The media guidance application then stores(e.g., in storage 408) the retrieved detailed information. In someembodiments, the media guidance application stores the retrieveddetailed information in non-volatile memory (e.g., flash memory) if itis available. In other embodiments, the media guidance applicationstores the retrieved detailed information in volatile memory (e.g.,SRAM).

Process 600 continues to 608, where the media guidance applicationreceives (e.g., via control circuitry 404) a second user selection tonavigate to a second group of media assets. For example, the mediaguidance application may receive (e.g., via control circuitry 404) auser input (e.g., via user input interface 410) selecting a differentgroup of media assets. For example, the media guidance application mayfirst have received (e.g., via control circuitry 404) a request to viewmedia assets identifiers in a video-on-demand guide and later receives arequest to view media asset purchases. In some embodiments, the secondplurality of media asset identifiers are stored in memory. For example,the media guidance application may be unable to store detailedinformation relating to media assets a user has purchased, but may beable to locally store (e.g., in storage 408) identifiers of media assetsthe user has purchased.

Process 600 continues to 610, where the media guidance applicationretrieves (e.g., via control circuitry 404), from the databasecontaining media asset identifiers associated with groups of mediaassets, a second plurality of media asset identifiers corresponding tothe second group of media assets. For example, as discussed above withrespect to step 604, the media guidance application may similarlyretrieve (e.g., via control circuitry 404) the second group of mediaasset identifiers. For example, the media guidance application mayaccess (e.g., via control circuitry 404) the media guidance databasecontaining media asset identifiers associated with groups of mediaassets stored locally (e.g., in storage 408) or remotely (e.g., at mediaguidance data source 518 via communications network 514). The mediaguidance application may query (e.g., via control circuitry 404) themedia guidance database for a specific set of media asset identifiersassociated with the second group of media assets (e.g., a purchasesscreen) and retrieve the identifiers.

Process 600 continues to 612, where the media guidance applicationcompares (e.g., via control circuitry 404) a first respective entry inthe database for each media asset identifier of the first plurality ofmedia asset identifiers with a second respective entry in the databasefor each media asset identifier of the second plurality of media assetidentifiers. For example, the media guidance application may execute(e.g., via control circuitry 404) a program script containing a for-loopto iteratively compare each media asset identifier in the firstplurality of media asset identifiers and each media asset identifier inthe second plurality of media asset identifiers. The media guidanceapplication may retrieve (e.g., via control circuitry 404) data storedin entries associated with each media asset identifier of the first andsecond plurality of media asset identifiers to compare. For example, themedia guidance application may retrieve from the database (e.g., storedlocally in storage 408 or remotely at media guidance data source 518accessible via communications network 514) characters of media assetidentifiers and/or metadata associated with the media asset identifiersto compare.

Process 600 continues to 614, where the media guidance applicationdetermines (e.g., via control circuitry 404) a first subset of mediaasset identifiers, the first subset comprising each media assetidentifier of the second plurality of media asset identifiers where datain the first respective entry matches data in the second respectiveentry. For example, the media guidance application may store (e.g., viacontrol circuitry 404) an indication (e.g., on a list or other datastructure in storage 408) containing an identifier (e.g., a string ofalphanumeric characters) of each media asset identifier of the secondplurality of media asset identifiers where a match between the firstplurality of media asset identifiers and second plurality of media assetidentifiers has been determined. Specifically, the media guidanceapplication may determine (e.g., via control circuitry 404) a matchbased on comparing characters of two media asset identifiers (e.g.,retrieved by the media guidance application from entries associated withthe media asset identifiers in the database) and determining eachcharacter is identical and in the same order (e.g., based on indexingthe characters). As described below with respect to FIG. 8, the mediaguidance application may determine a match even if each character is notidentical. Upon determining a match, the media guidance application mayexecute (e.g., via control circuitry 404) an instruction to write anidentifier of the matched media asset identifier to a list defining thefirst subset.

Process 600 continues to 616, where the media guidance applicationdetermines (e.g., via control circuitry 404) a second subset of mediaasset identifiers, the second subset comprising each media assetidentifier of the second plurality of media asset identifiers where datain the first respective entry does not match data in the secondrespective entry. For example, the media guidance application mayexecute (e.g., via control circuitry 404) the program script describedabove with respect to step 612 for comparing media asset identifiers inthe first and second plurality of media asset identifiers and sort(e.g., via control circuitry 404) any media asset identifiers unique tothe second plurality of media asset identifiers into a list or otherdata structure (e.g., stored in storage 408). For example, the mediaguidance application may, for each media asset identifier of the secondplurality, retrieve (e.g., via control circuitry 404) data to comparefrom every media asset identifier of the first plurality. If none of thedata compared (e.g., characters of the identifiers) match, then themedia guidance application may execute (e.g., via control circuitry 404)an instruction to write an identifier of the media asset identifier forwhich none of the data matches to a list or other data structuredefining the second subset (e.g., where detailed information has notalready been retrieved from the remote server).

Process 600 continues to 618, where the media guidance applicationretrieves (e.g., via control circuitry 404) detailed information foreach media asset identifier in the first subset of media assetidentifiers from memory. For example, the media guidance application hasalready retrieved (e.g., via control circuitry 404) the detailedinformation for each media asset identifier in the first subset from theremote server (e.g., media guidance data source 518 accessible viacommunications network 514). The media guidance application may store(e.g., via control circuitry) the detailed information in volatilememory (e.g., DRAM or SRAM) due to not having enough non-volatile memoryavailable to store the detailed information permanently. Since thedetailed information has already been retrieved (e.g., via controlcircuitry 404) for each media asset in the second subset, the mediaguidance application retrieves (e.g., via control circuitry 404) thedetailed information from the corresponding blocks of memory (e.g.,storage 408) where it is stored instead of transmitting a request forthe detailed information to the remote server (e.g., media guidance datasource 518 accessible via communications network 514), minimizingtransactions with the remote server and also maximizing the speed atwhich the second group of media asset identifiers can be loaded.

Process 600 continues to 620, where the media guidance applicationretrieves (e.g., via control circuitry 404) detailed information foreach media asset identifier in the second subset of media assetidentifiers from a remote server. For example, for media assetidentifiers where the detailed information has not been receivedpreviously (i.e., each media asset identifier in the second subset), themedia guidance application retrieves (e.g., via control circuitry 404)the detailed information from the remote server (e.g., media guidancedata source 518 accessible via communications network 514). For example,as described above for retrieving detailed information for the firstplurality of media assets, the media guidance application transmits(e.g., via control circuitry) a data packet to a remote servercontaining each media asset identifier in the second subset. Forexample, the media guidance application may transmit (e.g., via controlcircuitry 404) the data packet including a single media asset identifieror a list or other suitable data structure of media asset identifiers.The media guidance application may then receive (e.g., via controlcircuitry 404), from the remote server, the detailed information foreach media asset identifier in the second subset.

FIG. 7 is a flowchart of illustrative steps for retrieving media assetidentifiers in response to a user selection, in accordance with someembodiments of the disclosure. For example, a media guidance applicationimplementing process 700 may be executed by control circuitry 404 (FIG.4). It should be noted that process 700 or any step thereof could beperformed on, or provided by, any of the devices shown in FIGS. 4-5.Process 700 starts at 702, where the media guidance application begins(e.g., via control circuitry 404) a process for retrieving a pluralityof media asset identifiers in response to receiving a user selection.For example, the media guidance application may initialize the necessaryvariables and execute (e.g., via control circuitry 404) a program scriptcalling a particular method to execute process 700.

Process 700 continues to 704, where the media guidance applicationdetermines (e.g., via control circuitry 404) that the user selectioncorresponds to a navigation request. For example, the media guidanceapplication may maintain a table (e.g., stored in storage 408) of userinputs mapped to appropriate actions (e.g., executable instructions).Based on comparing (e.g., via control circuitry 404) the received userselection (e.g., via user input interface 410) with the table, the mediaguidance application may determine (e.g., via control circuitry 404)that the received user selection corresponds to a navigation command(e.g., any command to navigate to a different media asset identifier orset of identifiers). For example, the media guidance application mayreceive (e.g., via control circuitry 404) a user selection of an “UP”command using a remote control. Based on comparing an identifier of thecommand (e.g., “UP”) with the table, the media guidance application maydetermine that the received user selection corresponds to a navigationrequest.

Process 700 continues to 706, where the media guidance applicationdetermines (e.g., via control circuitry 404) whether the navigationrequest corresponds to a request for a new display screen. For example,the media guidance application may currently be generating for display(e.g., on display 412) ten media asset identifiers. If the user hasnavigated to the first media asset identifier and the media guidanceapplication receives (e.g., via control circuitry 404) a user input ofthe “UP” command (e.g., via user input interface 410), then the mediaguidance application may determine (e.g., via control circuitry 404)that the request corresponds to a request for a media asset identifierthat is outside the bounds of the current display screen. For example,the media guidance application may access (e.g., via control circuitry404) a data structure (e.g., stored locally in storage 408 or remotelyat media guidance data source 518) defining commands that, when receivedwhile a particular media asset identifier is selected, correspond to arequest for a new display screen. The data structure may be stored withdata defining the structure of media asset identifiers (e.g., theirorder when presented to a user) and may be arranged as a table whereeach entry is for a media asset identifier and contains field(s)defining commands that may be received that result in a need for themedia guidance application to retrieve another display screen. As aspecific example, an entry for the first media asset identifier maycontain a field that identifies the “UP” command as a command thatresults in a request for a new display screen. As another example, a“VOD” command may correspond to a request to access a new display screenwith video-on-demand media asset identifiers.

If at step 706 the media guidance application determines the navigationrequest does not correspond to a request for a new display screen,process 700 continues to 708, where the media guidance applicationreturns (e.g., via control circuitry 404) that no media assetidentifiers need to be retrieved. For example, if the media guidanceapplication determines (e.g., based on comparison with a table definingthe order of media asset identifiers presented to a user as describedabove with respect to step 706) that the navigation command does notrequire a new display screen to be generated, then no media assetidentifiers need to be retrieved since they are already generated fordisplay (e.g., on display 412). After returning an indication that nomedia asset identifiers need to be retrieved, process 700 may terminate.

If at step 706 the media guidance application determines the navigationrequest does correspond to a request for a new display screen, process700 continues to 710, where the media guidance application accesses(e.g., via control circuitry 404) a media guidance database containingidentifiers of groups of media assets associated with display screens.For example, the media guidance application may access the databasecontaining identifiers of groups of media assets associated with displayscreens locally (e.g., in storage 408) or remotely (at media guidancedata source 518 accessible via communications network 514). The databasemay be stored and/or integrated with the data structure described withrespect to step 706.

Process 700 continues to 712, where the media guidance applicationdetermines (e.g., via control circuitry 404) whether there is a storedidentifier of a group of media assets associated with the new displayscreen in the media guidance database. For example, the media guidanceapplication may execute (e.g., via control circuitry 404) a databasequery language script, such as SQL, to determine whether there is anon-null entry for an identifier of a group of media assets associated(e.g., in a field) with the new display screen. For example, the datastructure (e.g., as described with respect to step 706) may contain apointer to an entry in the database that contains an identifier of agroup of media asset identifiers corresponding to the received userselection. As a specific example, a received user selection of a “VOD”button on a remote control may cause the media guidance application toaccess (e.g., via control circuitry 404) an entry in the data structurefor the “VOD” command and retrieve a pointer to an entry in the databasecontaining identifiers of groups of media assets associated with displayscreens.

If at step 712 the media guidance application determines there is not astored identifier of a group of media assets associated with the newdisplay screen, process 700 continues to 708, where the media guidanceapplication returns (e.g., via control circuitry 404) that no mediaasset identifiers need to be retrieved. For example, the media guidanceapplication may determine (e.g., via control circuitry 404) that sinceno identifier of a group of media asset identifiers is stored in thedatabase, there are no media asset identifiers that need to beretrieved. For example, a command for a new display screen need notnecessarily result in media asset identifiers being displayed and couldbe a request to play a preview of a media asset, display news stories,etc. In these situations, the media guidance application would determine(e.g., via control circuitry 404) that no media asset identifiers needto be retrieved (e.g., since no identifier of an associated group ofmedia assets is stored).

If at step 712 the media guidance application determines there is astored identifier of a group of media assets associated with the newdisplay screen, process 700 continues to 714, where the media guidanceapplication retrieves (e.g., via control circuitry 404) the identifierof the group of media assets associated with the new display screen. Forexample, the media guidance application may execute (e.g., via controlcircuitry 404) an SQL script utilizing the “Select” command to accessand retrieve the identifier of the group of media assets (e.g., “VOD001”).

Process 700 continues to 716, where the media guidance applicationdetermines (e.g., via control circuitry 404) if there is an entry in themedia guidance database for the group of media assets including pointersto media asset identifiers associated with the group of media assets.For example, the media guidance application may store (e.g., locally instorage 408 or remotely in media guidance data source 518) a pointer toa location in memory containing media asset identifiers associated withthe new display screen. The pointer may be the identifier of the groupof media assets, or may be stored in an associated field in thedatabase. Alternatively, the media guidance application may search thedatabase for an entry including the identifier (e.g., “VOD_001”) of thegroup of media assets. The media guidance application may then access(e.g., via control circuitry 404) the entry and media asset identifiersassociated with the group of media assets and/or pointers to media assetidentifiers associated with the group of media assets. The mediaguidance application may determine (e.g., via control circuitry 404)that the entry in the database corresponding to the pointer is null. Inthis instance, process 700 proceeds to 718, where the media guidanceapplication returns (e.g., via control circuitry 404) that no mediaasset identifiers are available. For example, the media guidanceapplication may optionally transmit (e.g., via control circuitry 404) anerror message to the user and/or service provider as the presence of thepointer indicates that media asset identifiers should be available andlikely were moved to a different location in memory.

If at step 716 the media guidance application determines there is anentry for the group of media assets including pointers to media assetidentifiers associated with the group of media assets, process 700continues to 720, where the media guidance application determines (e.g.,via control circuitry 404) whether the media asset identifiers arealready stored in the local storage device. For example, as discussedabove with respect to FIGS. 1 and 6, the media guidance application maystore the identifiers of media assets locally (e.g., for media assets auser has purchased) but not the associated detailed information. Todetermine whether this is the case (and thus whether both media assetidentifiers and detailed information need to be retrieved) the mediaguidance application determines (e.g., via control circuitry 404)whether media asset identifiers associated with the group of mediaassets are stored locally (e.g., in storage 408). For example, the mediaguidance application may check to see for each locally stored mediaasset identifier whether the identifier of the group of media assets(e.g., “VOD 001”) is stored in an associated field. The media guidanceapplication may, alternatively or additionally, maintain a log ofidentifiers of groups of media assets where the media asset identifiershave already been retrieved and compare (e.g., via control circuitry404) with the log (e.g., a list stored in memory) to determine whetherthe media asset identifiers are already stored locally.

If at step 720 the media guidance application determines the media assetidentifiers for the group of media assets are already stored in thelocal storage device, process 700 continues to 708, where the mediaguidance application returns (e.g., via control circuitry 404) that nomedia asset identifiers need to be retrieved. For example, because themedia asset identifiers that need to be generated for display with thenew display screen are already stored locally (e.g., in storage 408),the media guidance application may terminate process 700.

If at step 720 the media guidance application determines the media assetidentifiers for the group of media assets are not already stored in thelocal storage device, process 700 continues to 722, where the mediaguidance application retrieves (e.g., via control circuitry 404), fromthe entry in the database, the pointers to media asset identifiers forthe group of media assets. For example, the media guidance applicationmay execute (e.g., via control circuitry 404) an SQL script to retrievethe contents of the entry in the database (e.g., to retrieve thepointer(s) to locations in memory storing the media asset identifiersassociated with the group of media assets). Process 700 continues to724, where the media guidance application retrieves (e.g., via controlcircuitry 404) the media asset identifiers from memory based on theretrieved pointers. For example, the media guidance application mayretrieve (e.g., via control circuitry 404) and store (e.g., in storage408) the media asset identifiers that are to be displayed as a result ofthe user selection (e.g., the navigation request).

FIG. 8 is a flowchart of illustrative steps for determining whether afirst media asset identifier corresponds to or exactly matches a secondmedia asset identifier, in accordance with some embodiments of thedisclosure. For example, a media guidance application implementingprocess 800 may be executed by control circuitry 404 (FIG. 4). It shouldbe noted that process 700 or any step thereof could be performed on, orprovided by, any of the devices shown in FIGS. 4-5. Process 800 startsat 802, where the media guidance application begins (e.g., via controlcircuitry 404) a process for determining whether a first media assetidentifier corresponds to or exactly matches a second media assetidentifier. For example, the media guidance application may initializethe necessary variables and execute (e.g., via control circuitry 404) aprogram script calling a particular method to execute process 800.

Process 800 continues to 804, where the media guidance applicationretrieves (e.g., via control circuitry 404) characters of the firstmedia asset identifier and characters of the second media assetidentifier. For example, the media guidance application may retrieve(e.g., via control circuitry 404 executing an SQL program scriptutilizing the “Select” command) a string of characters (e.g., “JamesBond: Goldfinger”) associated with a first media asset identifier of thefirst plurality of media asset identifiers (e.g., video-on-demandlistings) and a string of characters (e.g., “James Bond: Casino Royale”)associated with a second media asset identifier of the second pluralityof media asset identifiers (e.g., recent purchases).

Process 800 continues to 806, where the media guidance applicationcompares (e.g., via control circuitry 404) the characters of the firstmedia asset identifier and the characters of the second media assetidentifier. For example, the media guidance application may compare(e.g., via control circuitry 404) indexed characters of the retrievedstrings to determine whether each character matches.

Process 800 continues to 808, where the media guidance applicationdetermines (e.g., via control circuitry 404) whether the characters ofthe first media asset identifier match all the characters of the secondmedia asset identifier. For example, the media guidance application maydetermine (e.g., via control circuitry 404) that the first tencharacters (e.g., “James Bond:”) match, but the subsequent characters donot (e.g., no indexed character of “Goldfinger” matches thecorresponding indexed character of “Casino Royale”).

If the media guidance application determines that all the characters ofthe first and second media asset identifiers match, process 800continues to 808, where the media guidance application returns (e.g.,via control circuitry 404) that the first media asset identifier exactlymatches the second media asset identifier. For example, the mediaguidance application may determine that “James Bond: Goldfinger” is anexact match with a second media asset identifier “James Bond:Goldfinger.” Based on the identified match, the media guidanceapplication may retrieve detailed information for the first media assetidentifier already stored in storage (e.g., storage 408) and generate itfor display with the second media asset identifier, as described abovewith respect to FIGS. 1 and 6.

If the media guidance application determines that all the characters ofthe first and second media asset identifiers do not match, process 800continues to 810, where the media guidance application determines (e.g.,via control circuitry 404) if a threshold amount of characters of thefirst media asset identifier match the characters of the second mediaasset identifier. For example, the media guidance application maydetermine (e.g., via control circuitry 404) a number or percentage(e.g., 80%) of characters that match between the characters of the firstmedia asset identifier and the characters of the second media assetidentifier. The media guidance application may then compare (e.g., viacontrol circuitry 404) this to a threshold number or percentage ofmatched characters (e.g., 70%) and determine whether the amount orpercentage of characters matched between the first media assetidentifier and the second media asset identifier exceeds the threshold.

If the media guidance application determines that a threshold amount ofthe characters of the first and second media asset identifiers match,process 800 continues to 812, where the media guidance applicationreturns (e.g., via control circuitry 404) that the first media assetidentifier corresponds to the second media asset identifier. Forexample, the media guidance application may determine (e.g., via controlcircuitry 404) that since the media asset identifiers do not exactlymatch, but correspond, a subset of the detailed information between thetwo media asset identifiers corresponds and can be retrieved from localstorage. The media guidance application may then determine (e.g., viacontrol circuitry 404) that some detailed information should beretrieved from a remote server (e.g., if the media asset identifiers aredifferent episodes of a series, the director and actors may be the samebut the summary may be different).

If the media guidance application determines that a threshold amount ofthe characters of the first and second media asset identifiers do notmatch, process 800 continues to 814, where the media guidanceapplication accesses (e.g., via control circuitry 404) a data structurecontaining indications of whether media asset identifiers areassociated. For example, the media guidance application may access(e.g., via control circuitry 404) a data structure (e.g., stored eitherlocally in storage 408 or remote at media guidance data source 518)containing equivalent identifiers which may be organized as a tablewhere each entry (e.g., row) contains identifiers that are associatedwith the same media asset. The media guidance application may thenretrieve (e.g., via control circuitry 404) an entry in the datastructure for the first media asset identifier. For example, the mediaguidance application may execute (e.g., via control circuitry 404) aninstruction (e.g., an SQL program script utilizing the “Select” command)to retrieve, from an entry for a first media asset identifier, all otherassociated media asset identifiers (e.g., from fields associated withthe entry).

Process 800 continues to 816, where the media guidance applicationdetermines (e.g., via control circuitry 404) whether the first mediaasset indicator is related to the second media asset indicator based ondata retrieved from the data structure. For example, the media guidanceapplication may retrieve (e.g., via control circuitry 404), from fieldsassociated with an entry for the media asset identifier (e.g., “StarWars: Episode I”) media asset identifiers (e.g., “Star Wars: FirstEpisode,” and “Star Wars: Ep. 1”) indicated as equivalent media assetidentifiers. Based on comparing (e.g., via control circuitry 404performing character comparison as described above with respect to step806) the second media asset identifier to the retrieved equivalentidentifiers, the media guidance application can determine (e.g., viacontrol circuitry 404) whether they are related.

If the media guidance application determines that the first media assetindicator is related to the second media asset indicator based on dataretrieved from the data structure, process 800 continues to 812, wherethe media guidance application returns (e.g., via control circuitry 404)that the first media asset identifier corresponds to the second mediaasset identifier. For example, as described above, the media guidanceapplication may determine (e.g., via control circuitry 404) that sincethe media asset identifiers do not exactly match, but correspond, asubset of the detailed information between the two media assetidentifiers corresponds and can be retrieved from local storage (e.g.,storage 408).

If the media guidance application determines that the first media assetindicator is not related to the second media asset indicator based ondata retrieved from the data structure, process 800 continues to 812,where the media guidance application returns (e.g., via controlcircuitry 404) that the first media asset identifier does not exactlymatch or correspond to the second media asset identifier. For example,the media guidance application may execute (e.g., via control circuitry404) an instruction to write an identifier of the media asset identifierfor which none of the data matches to a list or other data structuredefining the second subset (e.g., where detailed information has notalready been retrieved from the remote server), as described above withrespect to FIGS. 1 and 6.
